Released: Exchange Server 2010 SP3

Earlier last year, we announced that Exchange 2010 Service Pack 3 would be coming in the first half of 2013. Later, we updated the timeframe to Q1 2013. Today, we're pleased to announce the availability of Exchange Server 2010 Service Pack 3, which is ready to download.

Service Pack 3 is a fully slipstreamed version of Exchange 2010. The following new features and capabilities are included within SP3:

  • Coexistence with Exchange 2013:Customers who want to introduce Exchange Server 2013 into their existing Exchange 2010 infrastructure will need the coexistence changes shipping in SP3.

    NOTE: Exchange 2010 SP3 allows Exchange 2010 servers to coexist with Exchange 2013 CU1, which is also scheduled to be released in Q1 2013. Customers can test and validate this update in a representative lab environment prior to rolling out in their production environments as an important coexistence preparatory step before introducing Exchange Server 2013 CU1.

  • Support for Windows Server 2012: With SP3, you can install and deploy Exchange Server 2010 on computers that are running Windows Server 2012.
  • Support for Internet Explorer 10: With SP3, you can use IE10 to connect to Exchange 2010.
  • Customer Requested Fixes: All fixes contained within update rollups released before SP3 will also be contained within SP3. Details of our regular Exchange 2010 release rhythm can be found in Exchange 2010 Servicing.

In addition to the customer reported issues resolved in previous rollups, this service pack also resolves the issues that are described in the following Microsoft Knowledge Base (KB) articles:

Exchange 2010 SP3 FAQ

Here are answers to some frequently asked questions.

  • Q. Does Exchange 2010 SP3 include the fixes in Exchange 2010 SP2 RU6?
    A. Yes. Service Packs are cumulative - they include all fixes included in previous RUs and service packs. Although Exchange 2010 SP2 RU6 was released on the same day as Exchange 2010 SP3, fixes in RU6 are included in SP3.

  • Q. Does Exchange 2010 SP3 include the security fix mentioned in Microsoft Security Bulletin MS13-012?
    Yes, fix for the vulneraiblity in MS13-012 is included in Exchange 2010 SP2 RU6, and (as stated above) fixes from SP2 RU6 are inclued in SP3. We recommend reviewing the related security bulletin before applying an update that contains security fixes.

  • Q. Why release RU6 for SP2 at all if all fixes are included in SP3?
    Exchange 2010 SP2 is a supported service pack (see Exchange Server Support Lifecycle). Customers typically deploy update rollups quickly but take longer to deploy service packs.

  • Q. Is Exchange 2010 SP3 compatible with WMF 3.0/PowerShell 3.0?
    A. Exchange team has validated and supports Exchange 2010 SP3 running on Windows Server 2012, which comes with PS 3.0 by default. Please note that even when running on Windows Server 2012, Exchange 2010 SP3 will still use only PowerShell 2.0 functionality. Exchange team has not validated Exchange 2010 SP3 running on earlier server OSes (2008, 2008 R2) with WMF3 / PS3 installed, and we therefore do not recommend that configuration.

  • Q. Does Exchange 2010 SP3 require an Active Directory schema update?
    A. Yes, as mentioned in Exchange 2010 SP3 Release Notes, an Active Directory schema is required.

  • Q. Can I install Exchange 2013 RTM in my Exchange 2010 organization after upgrading to Exchange 2010 SP3?
    A. As mentioned in the post, coexistence of Exchange 2013 in an Exchange 2010 SP3 org requires Exchange 2013 CU1, also scheduled for release in this quarter (Q1 2013).

  • Q. It's great that Exchange 2010 SP3 is supported on Windows Server 2012! Can I upgrade the OS my Exchange Server's running on from Windows Server 2008/2008 R2 to Windows Server 2012 after installing SP3?
    A. No. Upgrading the operating system after Exchange Server installation is not supported. You would have to uninstall Exchange, upgrade the OS, then reinstall Exchange. Or install Exchange 2010 SP3 on a fresh Windows 2012 install.

  • Q. Is MRM 1.0 supported on Exchange 2010 SP3?
    A. Yes, MRM 1.0 (Managed Folders) is a supported feature in Exchange 2010. We replaced MRM 1.0 management support in EMC with MRM 2.0 (Retention tags) in Exchange 2010 SP1. You can still use the Shell to manage MRM 1.0.

  • Q. Will I be able to restore and mount database backups created before a server is upgraded to SP3?
    A. Yes. When you restore and mount the database, it will be updated.

  • Q. Does Exchange 2010 SP3 add support for Active Directory Rights Management Services (AD RMS) in Cryptographic Mode 2?
    A. Yes, Information Rights Management (IRM) features in Exchange 2010 SP3 support AD RMS running in Cryptographic Mode 2.

  • Q. Is Exchange 2010 SP3 supported with <My great third-party Exchange add-on/tool>?
    A. Please contact the partner / third-party software vendor for this info. We recommend testing in a representative non-production environment before you deploy in production.

    How about some hosting guidance for 2013 now that we have a transition path?…/jj720331.aspx

  2. Nfields03 says:

    Just to confirm, is there a schema update with this SP?

  3. Gordon says:

    That's good news — released a bit earlier than I expected!

  4. Magnus Björk says:

    Thanks guys, great job!

    @Nfields03, yes there are Schema updates, more info in the Release Notes:…/jj965774(v=exchg.141).aspx

  5. Let the flood gates open for coexistence/migrations!

  6. Ajlan says:

    Finally! Excellent work! We been waiting for you :)

  7. Jon Webster says:

    Aww, Support for WMF 3.0 / Powershell 3.0 didn't make the short list of new features.

  8. Good to have some preparation time before Exchange 2013-CU1 comes out.

  9. Karsten says:

    All fixes contained within update rollups released before SP3 …

    As RU6 for Ex2010 SP2 is announced after SP3 are the fixes in RU6 included in SP3?

  10. Just to be clear.. We do NOT have to wait for 2013 CU1 to start transitioning to 2013, correct?

    Thanks for the update.


  11. Nino Bilic says:

    @ Christopher Meehan: Yes, you DO need to wait for E2013 CU1 to coexist with Exchange 2013 in production.

  12. Charles Derber says:

    Half good news until Exchange 2013 CU1 is released :)

  13. paul says:

    In a DAG how does the database schema get updated? Does it happen automagically when the non SP3 database becomes active on the SP3 server or is there some other magic. I didn't see anything stating the upgrade process for a DAG member.

  14. I guess I should re-phrase. The planning/testing can begin for migrations/coexistance; since 2013 CU1 is still required for prod environments.

  15. Nino Bilic says:

    @Paul, from release notes (…/jj965774(v=exchg.141).aspx):

    A database availability group (DAG) member that’s running an older version of Exchange 2010 can move its active databases to a DAG member running a newer version of Exchange 2010, but can’t do the reverse. After a DAG member has been upgraded to a newer
    Exchange 2010 service pack, its active database copies can’t be moved to another DAG member that’s running Exchange 2010 RTM or to a service pack that’s older than the service pack installed on the DAG member.

  16. Hiroki Asami says:

    @ Karsten: SP3 is not include SP2 RU6. see blow link.

    TITLE: Issues That Are Fixed in Exchange 2010 SP3


  17. justink says:

    So coexistence is STILL onhold until cu1… did you want to sell Exchange 2013?

    I have to confess I'm baffled by this product in the last few months after being a staunch Exchange champion for years.  

  18. John says:

    Unbelievable. First we have to wait for SP3 to have coexistence, now SP3 has finally arrived and we have to wait for CU1 again… Perfect way to plan things Microsoft!

  19. says:

    Is Windows Management Framework 3.0 and Powershell 3 compatible with Exchange 2010 SP3 or should we hold off with those still?

  20. Greg Taylor [msft] says:

    @ Casey – it will be soon Casey. As described in the article until CU1 for 2013 is out, you don't have a path. Keep an eye out later this week for a related post you might find interesting (as someone doing hosting/multi-tenancy).

  21. Andrew T says:

    Congrats on shipping this and the latest set of roll-ups! You'll forgive me If I wait a while to see if any version 2s appear though ;)

  22. Bharat Suneja [MSFT] says:

    @Hiroki @Karsten: Service Packs are cumulative and include all fixes from previous RUs. Exchange 2010 SP3 does include all fixes included in Exchange 2010 SP2 RU6.

    Issues That Are Fixed in Exchange 2010 SP3
    will be updated to include RU6.

  23. pesospesos says:

    You guys continue to boggle the mind.  Shifting the target again eh?  What is the point of releasing 2010 sp3 today if 2013 cu1 is not available?  Is it so the public can QA it for you and we can get sp3-v2 in time for CU1?  Oy vey.

  24. says:

    Oh, just wondering if the MS Forefront Protection 2010 for Exchange has any known issues with the SP3? As after updating the Exchange, my Forefront console tells me "The MS Information Store is running but the Forefront VSAPI Library is not registered."

    So far e-mails appear to be working, though not sure if the Forefront is doing its part. Just wondering if I was supposed to disable Forefront before the update and re enable it after even though that was fixed for the last rollup updates.

  25. JTTP says:

    Did you know that Exchange 2013 CU1 requires Exchange 2010 SP3v2 for coexistence?

  26. MarkLH69 says:

    Once we install E2k10 sp3, can we then install the Windows Mgmnt FrkmWrk 3.0 which includes Powershell 3.0 on our Windows 2008 R2 Exchange Servers (and also Win7 PCs than run the Exchange Mgmnt Consoles ) ?



  27. Bharat Suneja [MSFT] says:

    @vedru, @Jon, @MarkLH69: No. #MSExchange 2010 SP3 does not support .NET 4.5 & therefore WMF 3/ #PowerShell 3. See WMF 3 download page On Windows 2012, you can have .Net 4.5+WMF3+PowerShell 3 installed, but Exchange 2010 will require and use PS2.

  28. MarkLH69 says:

    What about Win7 with the Exchange Mgmnt Console on it ?

    Currently I cannot install the SCVMM 2012 sp1 console on my Win7 laptop without PowerShell 3.0

    Will installing Win Mgmnt Frmwrk and PowerShell 3.0 on my laptop for SCVMM stop my Excchange 2010 Mgmnt Console from working ? even with the sp3 update ?

  29. gerard says:

    I agree with pesos.

    <cynical>So what's next, 2013 CU1 will require RU1 for SP3 to co-exist?</cynical>

    Why did you guys even bother releasing the RTM version in the first place and waste our time and bandwidth downloading 3.5 GB of useless bits.

  30. Where can I find details of the Exchange 2010 SP3 Active Directory Schema Changes? The link supplied in the release notes currently only covers up to SP2  –…/dd877014(EXCHG.140).aspx

  31. Kristofer Ohman says:

    Thanks for clarifying 2013 CU1 and coexistance with 2010, but how about migrations?

    Is that possible given this release?

  32. Wimmer Christian says:

    @Gerard: Because not everyone is migrating to Exchange 2013.

  33. Jakke says:

    Any news about Coexistence with Exchange 2007 ?

  34. Grzegorz Wierzbicki says:

    From release notes:

    You can install Exchange 2010 SP3 only on computers that are running the Windows Server 2008 operating system with Service Pack 2 (SP2) and the Windows Server 2008 R2 operating system.

    I assume this is an error ?

  35. Greg Lambert says:


    So this means that we can start deploying Server 2012 domain controllers and prepare to full migration to Exchange 2013 when CU1 is out?



  36. tom says:

    During Upgrade process when it comes to 'Restoring Services', all services will be set to disabled and the upgrade process terminates, due to the fact that all services are disabled and can't be started during the next steps. Even setting them to manual or automatic, they will be set back to disabled after a few minutes.

  37. John C. Kirk says:

    Could you update the Exchange Server Supportability Matrix?…/ff728623(v=exchg.141).aspx

    There are a few gaps in that:

    * Several tables don’t mention Exchange 2013 (AD/domain/web browser/Clients/Tools/.NET Framework/PowerShell/MMC/Installer).

    * The Clients table doesn’t mention Outlook 2013.

    * Several tables don’t mention Exchange 2010 SP3 (Tools/Powershell/MMC/Installer).

  38. David says:

    When will the new CDO/Mapi tools be released?


  39. John says:

    When Exchange 2013 CU1 is released and co-existence is officially supported, will 2010 SP3 be required on all Exchange 2010 servers?  We have a very unusual co-managed environment with subdomains. I need to know if I'll need to coordinate with all the subdomain admins to get everyone up to SP3 before I can deploy Exchange 2013 in the root domain.

  40. WhyBotherTesting says:

    …and here I was like everyone else complaining about E2013 CU1 not being available.  I was planning on installing SP3 immediately into production (with no testing), as well as deploying 2013 into production…all at the same time.  What boggles the mind is not the release schedule from MS, but the lack of testing people seem to do before wanting to blast it into production.  I guess those are the same that then complain something broke since "MS doesn't test anything".  Personal responsibility?  Bah.  It's MS's fault.

  41. Jarrett says:

    So — i'm confused…

    Is RU6 for SP2 slipstreamed into SP3, or are they seperate updates?

  42. neconnn says:

    "…2010 SP3 brings update to AD & database schema. As a result, when mailbox servers are upgraded to Exchange 2010 SP3, the databases are upgraded to the SP3 version of the database schema. After a database has been updated to the SP3 schema, it can’t be mounted on a pre-SP3 mailbox server…"

    What if i need to restore pre-sp3 backup of my database?  Can i mount pre-SP database on a SP3 updated server?

  43. jim says:

    @ Bharat Suneja [MSFT], when will Exchange 2010 be compatible with WMF 3.0. If the CU1 for Exchange 2013 will address the interoperability issues between 2010 and 2013 it seems to be a bad decision on the Exchange Team's part to then require two different versions of PS to manage an Exchange environment

  44. Chris Branca says:

    Hi all,

    I was excited when I heard that SP3 for Exchange 2010 has been released. However, I am hitting a road block. I am aiming to use Exchange 2010 SP3 as an Edge in my DMZ on Server 2012. I was under the impression from Exchange blog that 2010 Edge will work
    on Server 2012 with Ex2k10 SP3 release.


    You can install Exchange 2010 SP3 only on computers that are running the Windows Server 2008 operating system with Service Pack 2 (SP2) and the Windows Server 2008 R2 operating system.

    However, on the blog post from Exchange team yesterday:…/released-exchange-server-2010-sp3.aspx

    Support for Windows Server 2012: With SP3, you can install and deploy Exchange Server 2010 on computers that are running Windows Server 2012.

    There is a varying difference of information here.

  45. DejanR says:

    Is MRM 1.0 still supported in SP3?

  46. Nino Bilic says:

    @neconnn – yes you can restore the pre SP3 backup; however during the mounting of the database on the SP3 server, we will upgrade the schema of the restored database. It should be seamless however be aware of it as then you cannot take this database and mount it on an non SP3 server.

    @pesos, @gerard, @whybothertesting – while I understand where you are coming from, it is assumed that – SP3, being a large update, will take some time to test and deploy in production environments on it's own, whether it provides E2013 coexistence or not. As another commented mentions – not everyone needs to coexistence piece anyway. CU1 is needed and we hear that, and will deliver it soon.

  47. Nino Bilic says:

    @Chris Branca – thank you for catching that, I have reported an error in release notes!

  48. Nino Bilic says:

    @DejanR – we did not take away features in SP3. :)

  49. Nino Bilic says:

    @Jakke – assuming that you mean "coexistence of Exchange 2007 and Exchange 2013" – please see this:…/released-update-rollup-6-for-exchange-server-2010-sp2-and-exchange-2007-sp3-ru10.aspx

  50. Vinícius Ferrão says:

    Let-me understand it correctly:

    In a existing Windows Server 2008R2 with Exchange 2010 SP2 Scenario we can deploy Exchange 2010 SP3 in upgrade mode, then upgrade Windows Server 2008R2 to Windows 2012 Server, and then finally raise forrest functional level to Windows Server 2012?

    That's the way?

  51. @Vinícius, upgrading an OS with Exchange already installed is not supported.

  52. says:

    After Updating, is impossible to reinstall the previously uninstalled UM language packs, as the SP3 update require.

    The new downloaded files, like: "UMLanguagePack.xx-XX.msi", downloaded from MS, cannot be installed using the documented procedure: /AddUmLanguagePack:xx-XX /s: … etc.

    The answer is always: UMLanguagePack.xx-xx.exe not found.

    Trying to execute the .msi directly also doesn't work.

  53. Vinícius Ferrão says:

    @Brian this should be mentioned in the release notes…

    So, to finally go to Windows Server 2012 we will need another machine to set up Windows Server 2012 with Exchange 2010 SP3 (or Exchange 2013 CU1 when it's released), setup the coexistence, migrate everything and shutdown the old Windows Server 2008R2 to finally raise our domain functional level to 2012 Server?

    Thanks in advance,

  54. @Vinícius, yes that is the same procedure as previous releases such as when Exchange 2007 SP3 brought support for Windows Server 2008 R2. If you want to move to the newer OS you must build and migrate to new Exchange servers. The Domain and Forest functional levels are not related to Exchange member servers. Those have to do with with your Domain Controllers.

  55. jim says:

    @Brian Day, based on the FAQ above: Q. Is Exchange 2010 SP3 compatible with WMF 3.0/PowerShell 3.0?

    A. No. Exchange 2013 SP3 does not support WMF 3.0/PowerShell 3.0. Although on Windows Server 2012 you can have WMF3/PS3, Exchange 2010 SP3 will require and use PowerShell 2.0. Does this mean that you cannot install WMF3.0 on Server 2012 if you install Exchange 2010 SP3 or do you have to launch powershell in ver 2?

  56. Bharat Suneja [MSFT] says:

    @David: New MAPI/CDO was also released yesterday. See

  57. raman03 says:

    Technet library does not have Exchange 2013 co-existence with Exchange 2010 Sp3.  Would it take some time before it gets publised?

  58. Blacktoe3 says:

    Are there upgrade instructions available for installing SP3 into a current Exchange 2010 environment?

  59. Damien says:

    I'm also curious if you can install WMF 3.0 on a Windows 7 machine running the Exchange 2010 SP3 management tools.

    More and more things are needing PS 3.0 and this still being a blocking issue is problematic.

  60. Yuhong Bao says:

    I think what is meant that it is supported to run Exchange 2010 SP3 with PowerShell 3.0 installed, but Exchange 2010 SP3 will not use it and will instead use 2.0.

  61. On the download page is the build number correct? After installing SP3 on my SBS 2011 test server I get a build number of 14.03.0123.003, not 14.03.0123.004!

  62. Exchange Joe says:

    So does Server 2012 = Windows 8?  Would love to run EMC on a Surface Pro!

  63. Poi Man says:

    @Exchange Joe,

    There is no EMC in Exchange 2013. It is all web-based through the ECP or via PS.

  64. @Exchange Joe, yes 2010 SP3 Management Tools can be installed on Windows 8 64-bit. We're in the process of updating the supportability matrix to call it out. The only requirement is the machine must be domain joined.

  65. pesospesos says:

    Hi guys, appreciate the team engaging the questions here.  Looking forward to cu1.  Can you speak to any concerns WRT Lync 2013 integration – or are we ready to go once CU1 hits?

  66. alan says:

    If I have Exchange 2010 SP3 installed, and accidentally say ran /PrepareSchema and /PrepareAD from the 2013 RTM installation media, do I have a problem?  e.g. Can I still install Exchange 2010 Servers as I did not continue to install 2013 RTM?

  67. Peter Stutzinger[dogado] says:

    We're currently running Exchange 2010 SP2 in Tenant Mode (Hosting Mode from SP1). Can we update to SP3 or does the ad schema changes conflicts with /Hosting mode?

  68. @Alan, no worries…. you can continue installing more 2010 servers as long as there is still at least one 2010 server still in the org currently.

  69. Paul N. says:

    Any word on the erroneous "Post-move cleanup failed" and subsequent retries when moving a mailbox?  I didn't see anything about it in the RU6 notes.  

    That adds three unnecessary minutes to each mailbox move, and while that may not be a big dea in the long run, it's a bit of an issue while I'm still migrating from 2003.  :/

  70. @Paul N – Unfortunately, that fix did not make it into SP2 RU6 or SP3.  However a fix is on the way.  If this is becoming an problem for your migration, feel free to engage Microsoft Support as they can get you an interim update.


  71. says:

    @Ross Smith, is there a KB article or reference number for that issue/Interim update, we have the same issue as Paul N, and i'd like to get it resolved soon as possible. Would help to make the request easier. Ta.

  72. @Stevel99 – KB number 2763065 should help you with support.

  73. Huseyin Unal says:

    I just would like to install EMC on Windows 8 workstation and you know it's required schema update as well so if I update schema to SP3 during the EMC installation does it affect the existing Exchange 2010 SP2 organization which in the same Active Directory?

  74. says:

    AD RMS Cryptographic Mode 2 and Exchange 2010 Information Rights Management is supportable?

  75. randy says:

    Will i have to uninstall my third party cert (go daddy) and reinstall it to install SP3 like i did SP 2 does anyone know?

  76. @Huseyin, preparing only the AD schema will not affect the current 2010 SP2 servers in the org.

    @Randy, having to remove/reinstall a cert for a SP upgrade should not be required back in SP2 nor today in SP3.

  77. says:

    Thank you. Checked himself. Everything works (IRM and Transport Rules in AD RMS Cryptographic Mode 2).

  78. Paul N. says:


    KB 2763065 doesn't appear to be valid; I receive an "Oops! The page you are looking for may have a new location, or is no longer available" if I try to go to it directly, and I get "Sorry, no results found for: 2763065" if I try to search for it.  :(

  79. soder says:

    @Paul N. :that should be a hidden article, accessible only to paid customer. No money, no support :)

  80. Malek KEBBAB says:

    I currently have problems with Exchange Server 2010 SP2 installed on Windows Server 2010 R2. It generates a lot of errors, for example MSExchangeRepl (2141, 2121), MSExchange ADAccess (2114, 2102, 2080, 2078, 2068), MSExchangeIS (1121), MSExchangeSA (1031), MSExchangeMailSubmission (1027), MSExchangeRPC (1008). ..

    I hope that SP3 will solve these problems.

  81. says:

    hello. after installation of sp3 i have the problem, that some users cannot delete some emails from inbox. the user gets the message, that the message cannot be moved, already moved or deleted or access denied.

    i have a single server with all roles. w2008 r2 x64 , all win updates installed. before the sp3 we had definitively not these problems.

    any ideas?

  82. Paul N. says:

    @ soder

    I am a paid customer (Premier Support).  :p  I just never opened a case since it was a "Known Issue" since the introduction of (I think) UR 3.  

  83. Arjan says:

    According to the documentation, you don't need 2013 CU1 for Coexistence:

    Exchange 2013 Coexistence support

    You must install Exchange 2010 SP3 if you want to run Microsoft Exchange Server 2013 in a coexistence mode. You can't perform an in-place upgrade from Exchange 2010 to Exchange 2013. However, you can install an Exchange 2013 server into the existing Exchange 2010 organization after you install Exchange 2010 SP 3. For more information about how to install an Exchange 2013 server into the existing organization, see Install Exchange 2013 in an Existing Exchange 2010 Organization.

    After you perform this procedure, your organization will be running in a coexistence mode. You can maintain this mode indefinitely, or you can immediately complete the upgrade to Exchange 2013 by moving all resources from Exchange 2010 to Exchange 2013, and then decommissioning the Exchange 2010 servers. For more information about how to upgrade to Exchange 2013, see Upgrade from Exchange 2010 to Exchange 2013.

    It's also confirmed by a co-worker who performed a migration from 201 to 2013 in the same AD.

    @Sebastian Mair I am going to guess the users who can't delete messages are using Outlook in online mode.

    Set up mailbox account on a nother machine, just temporarily, to run Outlook in cached Exchange mode.

    The same thing happened to a few of my users. They were RDS thin client users is why we were using online mode.

  85. Nino Bilic says:

    @Arjan – thanks for bringing this up. I have submitted a request to have this modified.

    Please note that coexisting with E2013 RTM is not supported. It might appear that it does not matter for your specific scenario, but trust us when we say that CU1 is required for you to be in coexistence with Exchange 2013.

  86. Yuhong Bao says:

    Why was it delayed to SP1?

  87. ahwc says:

    We can't move to SP3 anytime soon because it requires schema change.  What's wrong with IE10 with SP2 RU5/6?


  88. aaron says:

    Can Exchange 2010 SP3 be installed onto SBS 2011 servers?

  89. Bharat Suneja [MSFT] says:

    @Sergey Bezpalov: Yes, AD RMS in Cryptographic Mode 2 is supported in Exchange 2010 SP3. FAQ updated and docs will be updated to reflect this.

  90. Davis says:

    Can anyone confirm that the Exchange 2010 EMC with SP3 will run on Windows 8?

  91. Paul Newell says:


    Per the FAQ:

    Q. Is Exchange 2010 SP3 compatible with WMF 3.0/PowerShell 3.0?

    A. No. Exchange 2010 SP3 does not support WMF 3.0/PowerShell 3.0. Although on Windows Server 2012 you can have WMF3/PS3, Exchange 2010 SP3 will require and use PowerShell 2.0.

    My thought is that 2012 can also mean Windows 8.  And Brian Day mentioned earlier:

    "@Exchange Joe, yes 2010 SP3 Management Tools can be installed on Windows 8 64-bit. We're in the process of updating the supportability matrix to call it out. The only requirement is the machine must be domain joined."

  92. pesospesos says:

    A little confused.  We have a 2008 R2 utility server that helpdesk uses for management of Exchange 2010, and now we need to add the Lync 2013 admin tools to it as well.  Lync 2013 admin tools require Powershell 3.0, so how can I make both sets of admin tools function on the same 2008 r2 server?

  93. Davis says:

    @Paul Newell

    Thanks for your response….I had read the comments here and the FAQ….but I was hoping to get confirmation that it does actually work on Win 8 by someone who has tried it.  With 2012 and Win 8 sharing code base I was assuming that if it would install on 2012 then it would install on 8….

  94. Ron Woods says:

    So you tease us with the need for SP3 in Exchange 2010, then it gets released and now we find out we need to keep waiting for CU1 of 2013? They should have just waited to release them both at the same time…. Fail!

  95. Yuhong Bao says:

    Sorry, why was it delayed to Exchange 2013 CU1?

  96. Jennifer says:

    Same question as @MichaelChalmers which I didn’t find a reply to. Where is the information on the Active Directory schema update, the link provided only notes Exchange 2010 SP2 and lower, not SP3.…/dd877014(EXCHG.140).aspx

  97. Bharat Suneja [MSFT] says:

    @MichaelChalmers @Jennifer: We're working on updating Microsoft Exchange Server Active Directory Schema Changes Reference. Stay tuned – we'll announce once it hits the Download Center.

  98. Outlook 2003 SP3 is supported anc compatible with Exchange 2010 Service Pack 3?

  99. mike says:

    Can I use

    Exchange Web Services Managed API 1.2

    with 2010 sp3



  100. Kevin says:

    If we apply the 2010 SP3 schema to our forest, will we need to apply an additional schema update from the Exchange 2013 CU1 update, or once 2013 CU1 is released will we be able to install 2013 CU1 without the need for additional schema extensions ontop of the 2010 SP3 extension?

  101. Bharat Suneja [MSFT] says:

    @Kevin: Exchange 2013 CU1 includes additional Active Directory schema changes.

  102. Bharat Suneja [MSFT] says:

    @Lorenzo Soncini: There’s no change to client support for Exchange 2010 w/SP3. See

    Exchange 2010 System Requirements

    Support for Outlook and Entourage

  103. mderosia says:

    Normally in a DAG update I would suspend the passive copy of the DB on the server being updated. If I only have 2 members in my DAG and I move all databases to member #1 and I suspend DB copies on member #2 then update to SP3, should I not re-enable those copies after the update of member #2? I will need to re-enable those copies and move all DBs over to the updated server which will cause the updated database copies to replicate to the non-SP3 server. Will this be an issue? I am trying to lay out my plan for the update but that is where I am stuck if the SP3 database cannot be on a non-SP3 server.

  104. pesospesos says:

    If we are in a hybrid situation with ex2010 on prem and just using o365 for archive mailboxes, will we be able to move to ex2013 on prem upon cu1 release?  A post in the exchange online comments appears to say that is not the case.  Are we going to have yet another release to wait for???

  105. ML49448 says:

    Quote – "Service Pack 3 is a fully slipstreamed version of Exchange 2010"

    How do I install Exchange 2010 SP3 on a new build of Server 2012? The download is only 500 ish MB so I don't think it is a full install. Do I extract the files in the service pack to a local directory and run the installer from there presumably with the Exchange 2010 SP1 DVD in the CD drive? Or do I need to slipstream the service pack in to Exchange 2010 SP1 DVD? Or is the SP3 installer enough by itself to do an install of Exchange 2010?


  106. StephenKCEE says:


    Exchange 2010 SP3 extracts to approx. 1.5Gb and is enough by itself. In very simple terms, just extract to a local folder and run setup. No DVDs are required.


  107. Jason says:

    Can this be installed in a hosted exchange setup?

  108. Hello Exchange Team,

    I have a question about SCOM 2012 monitoring.

    Do you think that applying the SP3 on Exchange Box can break up the Monitoring part of SCOM, cause I don't see any new MPs version released since the Exchange SP3 was announced.

    In advance thank you.

  109. Yair says:

    When I try to read about sp3 (first option in the first setup screen) I get exchange 2013 and not 2010

    what going on ????

  110. AlanC says:

    Hi Guys,

    I get the following error when trying to install Ex2010 Sp3:

    Some Control aren't valid:

    – the current exchange server installation path does not have sufficient disk space to install the server roles selected.

    Please help!

  111. satya11 says:


    Hope you have sufficient space on c drive or where exchange folder reside.

    If you are using virtual environment there should be lot of space on LUN or respective storage..

  112. Peter H says:

    I have upgraded an admin pc but cannot now connect to the server which is running SP2 RU4. Is this SP not backwards compatible ?

  113. Dave says:

    Installed on 6 CAS (3 array) – 4 without any problem but in the last two (of course all the bosses and the Director of the used just them) Outlook anyware was broken with error

    Event 1310, ASP.NET 2.0.50727.0

    file C:WindowsSystem32RpcProxyweb.config was not updated and string, after replacing the file with the another server it worked fine.

    look like this string killed him from:

  114. Mottie says:

    The Active Directory Schema Changes Reference document which was updated today claims that the rangeUpper should be 14733 which I believe is a typo. The actual value is 14734.

  115. Nino Bilic says:

    @Mottie – thanks, should be fixed now :)

  116. Jason says:

    "Customers can test and validate this update in a representative lab environment prior to rolling out in their production environments as an important coexistence preparatory step before introducing Exchange Server 2013 CU1."

    What should we expect NOT to work when testing this in a lab?  It seems that it will either work or it wont – what can we learn from testing without CU1?  That it does not work?

  117. Martijn says:

    Upgrading Exchange 2010 SP2 to SP3 on Multi-Role Server. All steps get completed status but Languages , Hub Transport Role and Client Access Role each take 1 hour to complete. Is this 'normal'?

  118. sreenivasa says:

    can i install SP3 on CAS server and still maintain with SP2 on mailbox servers?  reason why i am asking is some of the backup products still not  working for SP3

  119. kannan says:

    as of my knowledge exchange 2010 with sp3 media is not available only sp3 available ,it will support to install exchange 2010 with SP1 (with out SP3) on windows server 2012 server

    after that can upgrade to SP3 on windows server 2012 or will support only exchange 2010 SP3.

  120. João Pedro says:

    I've updated the Exchange 2010 to SP3 to solve the issue in I.E 10 when I try to drag and drop e-mails in OWA using Windows 7. But the problem was not solved! Is there any solution? I'm not able to update the I.E 10 in my enterprise until this issue be solved. I'm looking forward for a solution.

  121. Holly says:

    I will be upgrading from Exchange 2010 SP1 RU8 to SP3.  I do not see an update to the base language packs for SP3, however thre was one for SP2.  Should I install the SP2 language pack (not UM) when I go from SP1 to SP3?

  122. Sagar says:

    Does Exchange 2010 powershell snap in supports .Net 4.0 with powershell 2.0 ? I am asking this because my .net 3.5 built application is running properly but not .net 4.0 built application.

  123. Michael Sage says:


    Similar comment to earlier…. We have Exchange 2010 and Lync 2013…. how do we powershell for the two? Given that Exchange 2010 *still* doesn't support PS3. Heeeelllllpppp!

  124. Mahesh Adate says:

    What about article…/2668686 and…/2810617

    in connection with upgrading Exchange 2010 SP1 to SP3

    Which document is correct……….
