Ask and you shall receive – Exchange 2007 SP3 w/support for Windows Server 2008 R2 Now Available

I am very pleased to let you all know that Exchange Server 2007 SP3 is available for download. As we highlighted in Updates to the Exchange Supportability Matrix this past November, this third service pack for Exchange 2007 enables Exchange 2007 to be installed on the Windows Server 2008 R2 version of the operating system. We heard you loud and clear that this is enormously important to our Exchange 2007 customers, so we worked quickly to deliver SP3 in order to meet this requirement.

Download Exchange 2007 SP3 here.

Keep the feedback coming and for those of you evaluating all the good stuff packed into Exchange Server 2010, don't miss the beta of Exchange Server 2010 SP1. You can read about SP1 here.

    Good to hear that……

    "What’s New in Exchange Server 2007 SP3" link is not updated!!

  2. susan says:

    Was there any beta process available to the public on this?

  3. Robert says:

    I’ve got one Exchange 2007 and one Exchange 2010 server and the setup says I need to do a Setup /PrepareAD. That seems odd.

  4. Kevin Bellinger (MSFT) says:

    @Pradeep: The link is fixed now, there was a slight delay in the redirect. Please let us know if you cannot find it still.

    @Susan: For this release there was not a public beta made available.

    @Robert: We made some schema changes in SP3 which will require you to extend the schema even if you have the RTM version of Exchange 2010. The changes are documented here:

  5. Nitin Gupta (gupnit) says:

    Guys – We will have lot of happy customers today !! Great Job !!

  6. Rob van Halteren says:

    Is the KB 982720 for CDO changes available somewhere ?

    The link does not work (yet?)

  7. John says:

    Hi guys,

    Since the Exchange Support Matrix has been moved, the URL now points to a page that is empty:

  8. Andrew says:

    This is great news! Just one question,  is it OK to run SP2 & SP3 servers side-by-side as we won’t be able to upgrade all of our servers at the same time?



  9. Robert says:

    Now I’m getting:

    Unified Messaging Server Role Prerequisites



    You must be a member of the Exchange Organization Administrators group to upgrade the first Unified Messaging server role in your organization to Exchange Server 2007 Service Pack 3.

    I checked – I am a member.

  10. Exchange says:

    Andrew – yes you can run a mix of SP2 and SP3 in the org.  However, keep in mind that CAS must be upgraded before Mailbox.  THe order of upgrade is:

    1.  CAS

    2.  HT

    3.  MBX

    And if you are running failover clusters, you don’t want to run a mix of Exchange versions either (because at some point you have to upgrade the CMS and after that happens you cannot failover/switchover to a lower version).


  11. Charlie Burchett says:

    I am glad to see the release of this SP.  Thanks!

  12. Exchange says:

    The Exchange Supportability Matrix update is now live –


  13. neo says:

    Is there a direct upgrade path from Exchange 2007 SP2 running on Windows Server 2008 to Windows Server 2008 R2?  Or would this be a rip and replace type of upgrade?

  14. Frank T says:

    Is it just me or does the supportability matrix indicate that Outlook 2010 is only supported with Exchange 2010 RTM and not any earlier version of Exchange? (conflicts with other things I’ve read)

  15. Jason says:

    Is there a KB with all of the fixes included in this SP?

  16. Frank T# says:

    Jason, describes the changes.

    The R2/Windows 7 support is the big one but there are a few minor changes around OWA, search indexing and disclaimers in some languages.

  17. Troy says:

    I have just installed the SP3 to have it fail on me, it said it couldn’t find the exchangeserver.msi file – but I could see it right there in the folder!  Now Exchange does not work at all, if I try and run the setup again it gives me the error that "binary files are not installed, but the backup settings registry key is present.  Only build-to-build upgrade mode is available"  Can’t find any info on this except for the same error when people tried to install SP1, any ideas?  My whole Exchange server is down!

  18. Frank T says:

    Troy, I’ve seen this when going from SP1 the c:windowsinstaller folder was "cleaned up" by someone in order to recover disk space (which isn’t something you should do.)  Could that be it?

    In that situation, I ended up blowing away the Exchange folders and registry keys (my databases were stored elsewhere) and then doing a /recoverserver using the service pack that was previously installed.  Then did my upgrade as a second step.

    This isn’t really supported though (for me it was in a lab) so I think your official path is an OS reinstall and Exchange /recoverserver or contact Microsoft to see if there’s a way to fix Windows installer repository.

  19. Troy says:

    Thanks Frank, unfortunately I don’t even have a C:WindowsInstaller folder…  I downloaded the SP3 file and saved it to C:Data… which is a share I created to store all our data.  So then I had to navigate to that folder, ran the file (which is basically just an extractor), then ran the setup.exe which appeared after extraction was complete.  In the same folder I could see other files and folders, including the exchangeserver.msi that it reportedly couldn’t find.

    You would think two things would have happened – first upon running setup.exe, it would check for all files to be in place before beginning the upgrade, and secondly if it failed to find a specific file, to give me a dialog box that lets me find it for the upgrade to continue!  Instead it just fails after already stopping and disabling services, removing files and getting everything prepped and ready for the install.

    I will have to do some more research on your suggestions, thanks.

  20. Frank T says:

    You should probably use the technet Exchange forums for help since these comments aren’t meant for that but I’ll just add that it was probably looking for the *old* exchangeserver.msi from the existing installation, because it wants to uninstall it.  Check the setup log to see what’s happening (c:exchangesetuplogs)     And C:windowsinstaller is a hidden system holder.

  21. chameleo says:

    I have successfully install SP3 on HT and CAS server. But when I try to install it on the passive node of CCR Clustered Mailbox server. I always get the following Error:

    Exchange Server component Mailbox Role failed.

    Error: Error:

    An error occurred. The error code was 3221685674. The message was Insufficient system resources exist to complete the request service.

    Log Name: Application

    Source: MSExchangeSetup

    Event ID:1002

    Can anybody tell me how to fix it? Thanks very much.

    Btw, after I failed to install SP3 on Mailbox server, I also get this Error:

    Windows cannot load the user’s profile but has logged you on with the default profile for the system.

    DETAIL – Access is denied.

  22. Kevin says:

    The Exchange supportability matrix lists Chrome, Safari, and Firefox as supported in OWA Premium mode! On first glance however, neither the latest release of Firefox (3.6.4) nor Chrome (5.0.375) allow you to choose that mode…. Any ideas?

  23. Bharat Suneja [MSFT] says:

    @Kevin: The matrix is being updated to correct the list of browsers supported for OWA Premium (and related Outlook 2010 support for Exchange Server versions – which currently shows only Exchange 2010). Cross-browser and cross-platform support for OWA Premium
    is an Exchange 2010 feature. See
    Outlook Web App Supported Browsers
    for details.

  24. Will the password reset functionality be coming to Exchange 2010 SP1 as well?

  25. Zabulon says:

    So we cant install Outlook 2010 with Exchange 2007???? that is what the support matrix said.  Can some one confirm?

  26. Exchange says:


    Outlook 2010 is supported against Exchange 2007 SP2 and SP3.  That was a mistake in the supportability matrix and will be corrected soon.


  27. Yakez says:

    Is there a KB with all of the fixes included in this SP?

  28. Graham says:

    Will i need a later version forefront for exchange before i install sp3?

    It was required for for sp1 and sp2

  29. kerry says:

    When I try to upgrade my Exchange 2007 SP3 server from 2008 to 2008 R2 it says Exchange is blocking it.  I let it get installer updates when I started the server upgrade process.

  30. Frank T says:

    Kerry, I don’t think upgrading the OS underneath Exchange is supported.  Check out the blog article linked above in the announcement

  31. wlunsford03 says:

    The link is fixed now, there was a slight delay in the redirect

  32. roland says:

    Hi all,

    after upgrading Exchange 2007 to Servicepack 3 we had the problem, that the OWA was reporting that the client has an old version of the S/MIME Plugin installed. Indeed the version of OWA is after upgrading and the S/MIME Plugin is

    Workaround is to add a DWORD entry ForceSMIMEClientUpgrade with value 0 under HKLMSystemCurrent Control SetServicesMSExchange OWASMIME.



  33. luco13 says:

    Im still running SP1 with RU9, do I need to install SP2 first or can I just go straight to SP3

  34. Bharat Suneja [MSFT] says:

    @Luco13: Service Packs are cumulative updates, so you don’t need to install a service pack you’ve missed and can install SP3 directly on a server that has Exchange 2007 RTM, SP1 or SP2 installed.

    In fact, starting with Exchange 2007 the update rollups also work similarly. You can install Exchange 2007 + latest service pack + latest roll-up, without having to look for individual hotfixes.

    See the Servicing Exchange post:

  35. G Man says:

    Are Forefront (old version) users required to run "FSCUtility.exe /disable" before installing this?

  36. Andrew says:

    Hi, is there a document for the process of installing SP3 on a SP2 SCC cluster? Or do I need to follow the same process as the SP2 install:

    1. run /m:upgrade on the passive node, reboot

    2. move the clustered mailbox server to the server and then run /upgradecms

    3. run /m:upgrade on the remainig node



  37. Exchange says:

    Andrew – you follow the same steps as identified in


  38. isol says:

    If we already have E2K7 SP2 running do we need to run all the AD prep commands  (i.e. setup /pl; setup /ps; setup /p; setup /pd) or just the schema update (i.e. setup /ps) to get SP3 working?  Also would E2K10 SP1 schema change be the same as E2K7 SP3 as it was for E2K10 SP0 and E2K7 SP2?

  39. When transitioning from 2003 to 2010, we would run the Exchange 2007 SP2 Schema update first so that we could have the option of putting a 2007 server in later if necessary (eg for some app requirement).

    Can we now just use 2007 SP3 for the same trick?

  40. yeminwin says:


    Any idea how to enable the password reset feature of Exchange 2007 SP3 if OWA is published at ISA 2006 SP1?

  41. Neil Pollicott says:

    How would I go about deploying this to a new standalone 2008R2 server? It won’t allow me to complete configuration. Is there an streamlined 2007 SP3 install available?


  42. SMB Helper says:

    Questions for SMB:  About to do a migration from

    SBS 2003 / W2003 Std to SBS 2008 on Windows Server

    2008 R2 Standard Edition running Exchange 2007.

    Current migration guides don’t mention Exchange 2007 SP3.

    What version of Exchange 2007 is on newly purchased and downloaded versions of Windows Small Business

    Server 2008 (SBS 2008)?  

    SBS 2008 comes with Windows Server 2008 R2 Standard

    Edition. (1 or more licenses depending on package)

    Do you need to run the Exchange 2007 SP2 Schema

    update first?

    I’ll report back what I find during migration.

  43. tummy tuck surgery says:

    I am also wondering the same thing yeminwin has asked.

  44. Jeff Guillet [MVP] says:

    Here’s an explanation of the new Exchange 2007 SP3 Password Reset Tool.

  45. Ernst Holzmann says:

    We use E2k7 for a hosted exchange solution.

    We followed the whitepaper for address list segregation.

    Is this supported by SP3?

  46. Rokman says:

    Is there a VHD of Exchange 2007 somewhere that I could download to test SP3?

  47. Andrew says:


    I need to install from scratch on a new 2008 R2 cluster, can I run the setup from the SP3 download or do i need to slip-stream SP3 into my original Exchange 2007 source?



  48. keithw says:

    I installed SP3 without apparent difficulty on Friday last. Now today Monday it would appear that the search facility within Outlook is not now working. I take it this is probably related to the changes in the Search Indexing but can’t seem to find a way around it…

    Anyone have similar experiences…or ideas on how to fix ?



  49. anyone tried SP3 yet together with a BIS 4.0 server? encountered any problems with blackberry server/devices?

    i’m still on SP1 because of BIS.

  50. FuchsK says:


    i have a Hyper-V VM (on a 2008R2 Host) with an Exchange Server 2007 SP3 installed (VM OS: 2008R2).

    We use Windows Server Backup on the Hyper-V Host for Backup the Host and the VM.

    Is this backup solution supported for Exchange 2007 SP3?

    Do i have to install vss writers or else for a correct backup and recovery solution?

    Thank you.


  51. jewellery says:

  52. Nigel Harvey says:

    Hit an issue trying Exchange 2010 recently Has anyone noticed that with Exchange 2010, you don’t get full access to commands in the Shell unless Outlook 2010 (x64 as well!) is loaded on the server?

  53. Greg Leatherwood says:

    We installed Exchange 2007 SP3 on our Exchange 2007 SP2 server (single server configuration).  SP3 apparently knocked out our ability to access documents remotely using OWA Remote Document Access.  I reported the issue and the MS support engineers are working on it.  Has anyone else experienced this?  

  54. Sean Hook says:

    Is it possible to have a 2007 CAS that has SP3, and still work with a MB/HT server that is say SP1? I want to do a swing migration to new servers, making the new CAS and MH/HT servers SP3, but leaving the existing ones on SP1. Ideally I would replace the current CAS server first – but from an initial test I did it did not appear that the CAS sould talk to the Non SP3 MB server.

  55. subrat says:

    What is the procedure to updgrade the MBX servers which are in CCR an SCR?

  56. Nick Laurent says:

    We’ve installed SP3 and now have two issues with OWA.

    – Autocomplete doesn’t work for email addresses

    – The cursor doesn’t start anywhere when drafting a message (either new or reply/forward)

  57. javiers says:

    I’m also having the same problem as Greg Leatherwood, any news about a fix for this?

  58. GhiglioneP says:

    This article on technet must be updated:

  59. FungHanL says:

    Great job listening to feedback! :)

    Will the password reset fix in SP3 – be finding its way into Exchange 2010 SP1? seems the same behaviour exists on 2010 RTM.

  60. justin says:

    How do you install this on Server 2008 R2 if you can’t install Exchange 2007 on Server 2008 R2 without SP3…? Looking for a slipstreamed Exchange 2007 with SP3 I guess.

  61. Exchange says:

    Justin – all Exchange 2007/2010 service packs are "slipstreamed". In other words – we ship the whole product with updated binaries. You do not need to install RTM first, just install SP3 and you are good to go.

  62. Al says:

    I need to install E2K7 SP2 in a brand new org.  For AD schema update, do I just go straight to E2K7 SP2 AD schema update or do I need to do E2K7 RTM schema update first?

  63. KellyK says:

    I had the same issue of "binary files are not installed, but the backup settings registry key is present.  Only build-to-build upgrade mode is available" and I finally figured out that I had to run the command suggested for the SP1 upgrade: /mode:upgrade and then it would still fail when trying to upgrade each role telling me that the service or one of it’s dependents was disabled. When I checked the exchange services, they had ALL been disabled and when I reset them back to automatic and ran the upgrade again, it would again disable all the services as it started each roles upgrade. I finally was able to see the services "disable" as the role upgrade started and if I reset them to "automatic" as each role was being upgraded I finally was able to make it through the upgrade and everything seems to be working correctly. Why, if the service needs to be started at the end of each roles upgrade would the services get disabled at the beginning of the upgrade instead of just stopped? Anyway, I hope this helps someone else.

  64. Ricky T says:

    I had a Windows 2003, Exchange 2007 box running hub transport, client access, and mailbox roles. When upgrading to SP3 (Direct from SP1) The upgrade’s to hub transport and client access completed ok, however the Mailbox role upgrade failed with the error "An error occurred. The error code was 3221684229. The message was Access is denied..".

    I looked in the Exchangesetup.log and found several Access Denied entry’s for "f:8.03.0083sourcesdevadminsrclibsbasebasemisc.cxx:1353"; this made no sense as the f: drive only contained log files.

    I re-ran SP3 setup, whilst monitoring it with Sysinternals Process Monitor and found a single Access Denied was logged, this was for a DeviceHarddiskVolume4. I found that the DeviceHarddiskVolume4 volume was mounted in a folder under the OWA IIS folder (In this instance: C:Program FilesMicrosoftExchange ServerClientAccessOwa). I removed this volume and then ran the setup again, this time SP3 installed correctly.

    I’ve posted this in case anyone else has this issue, as it is not apparent from the initial error message or Exchangesetup.log that the cause of this Mailbox role upgrade error lie’s within the ClientAccess folder.

  65. Ytsejamer1 says:

    I have a similar question as Justin… Can I just install all of Exchange 2007 SP3 with the SP or do I need specific Exchange 2007 SP3 media to get Exchange 2007 installed in a new or legacy 2003 environment?

  66. Allen S says:

    Don’t install SP3 if you are using Data Protection Manager to backup a CCR passive node cluster.  After the upgrade it breaks truncating transaction logs after the backup.  DPM reports a good backup.  We just caught the issue and it has completely destroyed our DPM backups as well as almost crashing our clusters from running out of disk space on the transaction log volumes.  We opened a case with MS Support and they are just aware of it now.  DON’T INSTALL SP3 IF YOU USE DPM TO DO CCR PASSIVE NODE BACKUPS!!!!!

  67. bbermingham says:

    Allen S, have you heard back from MS Support yet? We’re experiencing this same issue with BackupExec.

  68. kalam says:

    can anybody tell me how to update SP3 in following senerio;

    Exchange Mailbox Virtual Server (CCR-2 Nodes)

    mailboxsrv1 (Node1), mailboxsrv2 (Node2)

    Exchange Hub/CAS Servers (NLB – 2 Servers)

    hubcas1, hubcas2

  69. Allen S says:

    We heard back from MS Support that the product team is aware of the issue and they are working on an Interim Update apparently.  I really think they should post something though to make people aware of what’s going on.  If we wouldn’t have caught it in time we would have completely ran out of space on our clusters.  I’m glad we have monitoring in place.

  70. David H says:

    Anyone having issues after updating to SP3.

    Our users can no longer open documents when using the OWA site.

    If I choose "force web ready document viewing" then everything opens in the browser just fine.

    If I do not force this it opens a blank IE page and says done. Never prompts to open or download the document.

    Any ideas?

  71. Tyson N says:

    Hmm… I was hoping this SP would fix some odd calendar issues we are having, but we use BackupExec, so I am a bit nervous to try it. I guess I will wait a bit and see if MS releases a fix.

  72. la_bruin says:

    I can confirm that remote file access is broken with Exchange 2007 SP3.  I’ve tried everything and sure the documents are listed but when trying to open anything it just opens a blank page in any browser.  Oh yeah it also breaks Macintosh Entourage users running non Web Services Edition (using the old webdav protocol).  One word – UGH!

  73. abdul says:

    hello..  if i have 3 different office locations (chicago, london and sydney)..but are all part of the same domain.  All are currently E2K7 SP1.  Can i only upgrade one site …UK to SP3.  Will it affect any flow or intraoperability with the other offices?  And UK is proxying the webmail for Sydney…how will that be affected? if any.

    And it seems like the AD extensions are mainly for Unified Messaging from what I have read so far? or is there more to it than that?

    Thanks for your time and efforts.

  74. Abdul,

    Since your environment is E2007 SP1, when you extend the schema you will get the E2010 RTM schema extensions as well as the E2007 SP3 schema extensions (UM changes as well as some additional POP/IMAP security attributes).

    The order in which you upgrade your sites should be:

    1. External Facing site

    2. Internal Facing site

    So if the UK site is the site to which you have your users access OWA to get to their mailbox (which may be located in a downlevel site), then yes you want to upgrade it first.

    Also remember to upgrade them in the appropriate order, CAS, HT, and then MBX.


  75. abdul says:

    Thanks for the quick reply Ross.  So to clarify will I have to upgrade the other sites (chicago and sydney) to sp3 in order for OWA to work for the Sydney folks?  

    And will upgrading to SP3 cause any mail flow issues between UK and Chicago and Sydney if I dont upgrade the other sites to SP3.?

  76. Marco says:

    Is there a clean install procedure, to install Exchange 2007 on Windows 2008 R2? I’m doing this in a lab environment, installing Exchange directly from the service pack 3, and that seem to work. Is this approach correct?

  77. abdul says:

    Hey… do we have to use the to upgrade to sp3? or can we do it via the Setup wizard?  according to this article..

    it is saying to do it the same way as sp1 to sp2…or am I wrong to assume that?  in the lab I was able to use the wizard and go directly from SP1 to SP3…

  78. abdul says:

    nevermind..i finished reading the release notes for SP3.. my bad.

  79. Petri says:

    Thank you for offering support for R2, but is there any improvements for the tracking tool? Perhaps the only thing I’m missing from the E2003 is its tracking tool. E.g.:

    – you are not able to track single mailbox in one query, you have to search all HUBs in the same AD site

    – in a first result you are not able to see the recipients.

    Should I call it "loosing track tool"  ;-)

  80. Billy D says:

    Anyone try installing the service pack on a server not in the same site as the FSMO server?  Even though I already ran the Schema and AD preps the service pack fails because it is not in the same site.  Nothing in the tech notes.  Do i have to transfer the FSMO roles to the site to install the service pack?

  81. JD says:

    Did I miss something here? isnt this release supposed to get around the requirement for a 2k3 GC in a site ? and allow e2k7 to be deployed into a site with only 2k8 R2 DC/GC’s present.

    Ive been forced into a 2k7 deployment due to a vendor product that wont support 2k10 luckily I still have a 2k3 GC in the site that is due to remove this weekend. I ran the latest exbpa and end up with a critical error linked to here:

    Site not suitable for E2k7 or E2k10.

    Anyone else seen this. am I losing my mind? site has 2 * 2k8 R2 ver:7600 and 1 * 2k3 Sp2 Ver 3790 GC’s the 3790 is due to be decom’d asap. When I ran exbpa it stated the above and the 2k3 wasnt a GC, making it a GC and running exbpa again and all is well. states Active Directory Supported environments of 2k8 R2. no little & or * saying oh and by the way you should have a legacy GC just to keep the exbpa happy…. ??? help!

    Anyone? any input on this?

  82. Craig-au says:

    I have been trying to apply SP3 to Exch 2007 SP1 on Windows 2003 R2. Have had a few problems. Firstly it couldn’t do the upgrade because Symantec Mail Security for Microsoft Exchange was running, and had files locked, so I had to stop that service to get it started. Then it failed because it must have taken too long too stop a particular service (MSExchangeFDS?), and not option to go back and undo what was done, only "Finish".  Then it had disabled so many services (not sure which exactly, but certainly all the Exchange ones), it couldn’t run again becaue Remote Registry and IISAdmin were off. I turned those back on again, and progressed further, but couldn’t run because MSExchangeADT was disabled. I enabled and started that, and is progressing further again. Although I’m worried it won’t re-enable all the services it disabled, and that SMSMSE won’t work after upgrade either…

    How can I get a list of all the services that it automatically disabled?

    And by the way, why does it have an "undo" or "go back" option if it fails in the middle of the upgrade..?

    I’ve never done an SP install as messy as this before… :(

  83. Ben says:

    Every time I install SP3 in my test environment, it stops the exchange mail submission service from running and I can’t start it. Luckily it’s a VM so I can revert, but not very impressed and certainly wont be going live with this update!

  84. Bawnz says:

    Hi, I’ve upgraded my Exchange 2007 SP2 servers as well as installed new Exchange 2007 SP3 installations on Windows 2008 R2 servers in my test environment. But when I check my test environment’s schema using ADSIedit, the changes outlined in are not made. Is this because we aren’t utilizing the UM features in Exchange 2007, or is the setup just screwing up somewhere? I was curious so I ran setup.exe /ps to force a schema prep, which finally made the changes detailed above. So my question is, if I run setup and upgrade my SP2 environment in production(not using UM either) the same way I did in test, do I have to worry if these schema updates are made or not? Reason is, if the schema is going to be changed, our IT policy is to have a worst case scenario to roll back the updates, which like most of you, I feel is completely unneccesary for an Exchange SP that only modifies 14 fields.


  85. TomP says:

    Hi all,

    I’ve have SBS 2008 R2 with Exchange 2007 SP1 Rollup 9 installed. Should I upgrade to SP3? I’m having issue with outlook keep asking non domain laptop for password.

    Hi all,

    I’ve have SBS 2008 R2 with Exchange 2007 SP1 Rollup 9 installed. Should I upgrade to SP3? I’m having issue with outlook keep asking non domain laptop for password.

  87. Bill D says:

    Hey Tom,

    Yes.  Even rollup 10 for SP1 will clear up the issue with the password prompt.  

  88. atkscott says:

    FYI…the new password change functionality doesn’t work with W2K3 IIS6. It only works on W2K8 and IIS7. This was a pain to figure out. PSS didn’t even know this…

  89. David H says:

    Does anyone know if Microsoft has a fix or is planning a fix for the issues with opening files in OWA after moving to SP3?
