Exchange Server 2007 Series (Part 5 of 24) Questions and Answers Log (02-05-07)

Slowly but surely, I'm starting to get caught up.  Here's the Q&A Log from Part 5 on February 5th.  There are a few questions that I didn't have a complete answer for - ones that ask for dates.  I am continuing to research these items and will post a follow up when I get an answer.  Please let me know if I missed anything.

As of 7/27/07, I have made an update to this blog.  Please look for the section that begins with: ***NEW / UPDATE****.

Exchange Server 2007 Series (Part 5 of 24) Questions and Answers Log (02-05-07)

Question: Do you have recommendations when Migrating E2007 and ISA 2006 at the same time? (From A SBS server)

Answer: My personal recommendation would be to Migrate the ISA first and then Migrate Exchange. You would then need to re-publish Exchange through ISA 2006 using the update publishing wizards (if you are publishing Exchange to the outside world). This scenario is not specifically documented for SBS though so I cannot point you to any prescriptive migration guidance.

Question: Does Microsoft have any webcasts for Exchange 2007 that are above the 200 level?

Answer: If you search at you can search for archived and upcoming webcasts. Most have a level associated with them but, unfortunately, our search tool does not allow you to search on level.

Question: Do you need ISA 2006 with Exchange 2007 to publish OWA or will ISA 2004 work?

Answer: You can still publish Exchange 2007 using ISA 2004. ISA 2006 has some updated wizards to also accommodate Server to Server connectivity for Exchange server communications.

Question: I want to ask about exchange 2007 routiong , what if exchange found 2 site links with 2 equal costs how messages are routed

Answer: The Hub Transport will pick one of the routes.

Question: On a single server installation, obviously you would NOT configure an Edge transport role, correct?

Answer: In fact, a single Exchange server implementation you cannot have the Edge Transport server role. The Edge Transport server role must be installed on a server that is not a member of your production AD Domain.  The Edge Transport is an OPTIONAL role and cannot co-exist with any other Exchange 2007 server roles.

Question: Exbpa 2.7 (with current XML-updates) still shows the Exchange 2007 Readiness check is beta. Is this a problem and will it be corrected.

Answer: The ExBPA defaults to checking on the Internet for the latest set of best practices and updates to the ExBPA. Once the E2007 Readiness is out of beta, it should update automatically as long as you allow the ExBPA to check.  The fact that it still says “beta” will not cause any issues.

Question: do you have any recommendations for transitioning a FE/BE E2003 server on the perimeter to E2007 on the inside with ISA 2006 on the perimeter?

Answer: For this you should review the ISA deployment guide -- -- and the Exchange 2007 Deployment guide --  If I were to break it down to just a few simple steps, I would setup the ISA 2006 server first and be ready to create the publishing rules.  Then move the FE servers back into the “inside” and finish by publishing via ISA 2006.

Question: do you have a date for migration tools for Lotus Domino, to Exchange 2007?

Answer: I do not have a release date. Monitor the site as well as for Microsoft Transporter for Lotus Domino.  I have also asked the PM in charge of these tools and will post a response when I get confirmation.

Question: when migration PST files from 03 to 07 for mailboxes would you lose or retain Single Instance Storage

Answer: PST's are client based and do not impact SIS on the server DB's. The official migration process from ASCII based PST files (the old one with the 2gig limit) to the New UNICode format is to create a new, UniCode PST, drag and drop the mail from the old PST format and then delete the old PST.

Question: Are there migration tools from GroupWise to E2k7?

Answer: These tools do not exist at this time.  I am researching to find out if and when we will release GroupWise migration tools.

Question: Will there be a migration wizard type application coming out for Exchange 2007 or is the Transporter Suite 2007 for Lotus Domino the only additional tool? I would need to have a tool to migrate from POP/IMAP based email system.

Answer: is your best resource

Question: Why would mixed Exchange 2000 and 2003 not be supported for migrations? Is this not Exchange 2000 native mode?

Answer: Exchange 2000 and 2003 environments are supported for integration with Exchange 2007.  Please remember that “Mixed” mode refers to Exchange 5.5 being in the mix.

Question: If I am using SBS 2003 as a domain controller will there be any problems if I intend to add E2007 on the separate 64 bit system without upgrading SBS 2003 to the standard or enterprise edition?

Answer: You can do this, although the SBS Wizards will no longer function the same way. The SBS Wizards are designed to run against an E2003 server on the same machine. So while you can implement this, you would be left doing manual admin and configuration/maintenance.

Question: Which E2K3 APIs are no longer supported in E2K7?

Answer: For this you will need to research at the MSDN site --

Question: is the ADC supported with a CA(inter-org) into E2007?

Answer: If I understand this question correctly, the answer is “No”.  The ADC assumes co-existence with Exchange 5.5 which is not supported.

Question: Are there any (Upgrade)Tests (MCP) from Exchange 2003 to 2007?

Answer: Here is the course, I am not aware of a Cert Test for Upgrade -  Certification is at 

Question: Will OWA etc work for 2007 if still on 2003 FE servers?

Answer: If the mailbox is on an Exchange 2007 Mailbox server, you cannot use an Exchange 2003 FE for OWA. 

Question: is the lotus toolset available right now?

Answer: talks about availability

Question: why and not setup.exe?

Answer: is for command line unattended install.  Setup.exe initiates the graphical install.

Question: are you saying you can only have 2000 OR 2003 - not a mix of the two ?

Answer: The issue revolves around Exchange 5.5 which is what Mixed mode accounts for. You cannot have 5.5 in the mix, thus you need to be in 2000 or 2003 native mode.  You can have a mix of Exchange 2000 and Exchange 2003 servers so long as it is Exchange native mode.

Question: In a 2K3 and 2K7 mixed environment, are the new features of 2K7 still supported on any mailbox; or does it have to be honed on the 2K7 server store?

Answer: The new features would require the mailbox to be homed on the Exchange 2007 server.

Question: What methods beside exmerge can be used to move mailboxes from 2000 to a new 2007 exchange server?

Answer: You use Move Mailbox wizard from the Exchange Management Console or Move-Mailbox from the Exchange Management Shell.

Question: Does ExMerge work with E2k7 at all? I've heard it doesn't but haven't tested it myself.

Answer: No.  It is no longer a “supported” tool for Exchange Server 2007.

Question: When will more advanced documentation for migration be published? Is there a migration guide coming out as in Exchange 2003?

Answer: is more information on migration.

Question: i thought you couldnt use move mailbox wizard from exchange system manager - I thought you had to use the move-mailbox commandlet to move any mailboxes to 2007 ?

Answer: That is correct.  The previous answer was incorrect when referencing Exchange System Manager – I have corrected it to Exchange Management Console.

Question: How to enable full-text indexing on mail store?

Answer: It is enabled by default.  To disable / re-enable, you will need to use the Exchange Management Shell cmdlet: set-mailboxdatase.

Question: what is the advantage of using command console?

Answer: Scripting capabilities, my favorite is adding new users with a script, I can supply a text file with a list of users, user name, password and import several users at once.  There are some tasks that can only be performed from the Exchange Management Shell.

Question: What's this Hub transport server?

Answer: Hub Transport Server - Microsoft Exchange Server 2007 Hub Transport server role is deployed inside your organization's Active Directory. It handles all mail flow, applies organizational message routing policies Check out these links -

Question: Can CCR be configured in an Active+Active+Passive cluster?

Answer: No, CCR only supports Active / Passive.  See the following --

Question: If is the only information that is going to be published, I don't think many successfull migrations will take place. Does this mean that no additional documentation will be published?

Answer: We will continue to publish additional information. There is also the Exchange Team blog as well as many, many Exchange enthusiast’s sites you can capture additional information from.

Question: can we get a copy of this webcasts?

Answer: All Webcasts are recorded and made available at in 48-72 hours.

Question: Can the Client Access Server use the Hub Transport in a seperate site ?

Answer: The Client Access server role does not communicate with the Hub Transport, but the Mailbox.  You will need to have at least one Client Access server role in each AD site that has a Mailbox server role.

Question: Did you say that Outlook 2000 is no longer a supported client by MS

Answer: That is correct.  Outlook 2000 has fallen off the list of “officially” supported programs.

Question: In a front-end/back-end solution, when adding a 2007 backend server, will the front-end servers (2003) redirect properly to the new owa url ?

Answer: No.  You must introduce an Exchange 2007 Client Access server role before implementing an Exchange 2007 Mailbox server role.

Question: can you confirm MIIS GALSync is now tested and supporte dby MS into an E2007 org please/

Answer: This is what we use in house so it is tested in an “unofficial” manner.  I have not found any documentation that specifically outlines that this has been “officially” tested.

Question: How is 07 public folder technology going to integrate with OMA devices like versamail and blackberries ?

Answer: We do not support OMA in Exchange Server 2007.  We also do not have native support for Blackberry devices.

Question: do u need CAS & Hub transport srv EVEN if in mix Exchange 2003 AND 2007 mode then?

Answer: Yes.  Remember, you MUST have a Hub Transport and Client Access server role in every AD Site that has a Mailbox server role!

Question: Do you have to have a Hub Transport server in a site that does NOT have any Exchange servers?

Answer: For each Active Directory SITE that has a Mailbox Server role, you will need to have at least 1 Hub Transport server role.

Question: Is Outlook 2007 included with the DVD of Exchange 2007? Previous versions of Outlook were included with the Exchange media.

Answer: No, Outlook 2007 is not included; it is part of Office 2007.

Question: In Transition path, which server role should be installed FIRST into existing Exch2003 org, and is that required or recommended?

Answer: If you are doing a phased deployment of Exchange Server 2007, you will want to deploy the Client Access server role first.

Question: People are reading that these servers are needed "in every site" (period) -- please help reduce panic and clarify that you mean in every site where mailbox servers reside.

Answer: For each Active Directory SITE that has a Mailbox server role, you need to have at least 1 Hub Transport server role.

Question: How do we upgrade our E2K3 front-end servers to E2K7? Can the E2K3 servers be up at the same time as E2K7 servers?

Answer: There is no upgrade. It will always be a transition or migration. 2007 and 2003 can coexist at the same time.

Question: Can you NLB servers that have both the CAS and Hub Transport roles?

Answered Privately: Yes

Question: You would only syncronize public folders only if you use them correct? There is not a need for them otherwise?

Answer: Correct - ALSO if you will be using Outlook clients prior to OL2007, those versions use Public Folders for Free/Busy information so in that case you would also want to migrate them.

Question: Is there a template to build management agents in MIIS?

Answer: That I’m not sure of.  You will want to look at the home page for MIIS:

Question: For the E2k3 FE server question they need to replace their E2k3 FE servers with E2k7 CAS servers, which support e2k3 & e2k7 based mailboxes.

Answer: That is correct.

Question: I believe MS went pure E2007 rather than coexistence, so dog fooding of this scenario?

Answer: No, we did not.  We transitioned from an Exchange 2003 environment to an Exchange 2007 environment.  We did move mailboxes from our Exchange 2003 server to our 2007 servers as quickly as possible, but we had both versions co-existing for many months.

Question: We have only one forest and one AD site. We have no IP subnets defined. Is subnet definition required for mail flow to work?

Answer: Even if you only have one AD site, you should still define your IP subnet(s).  Regardless, mail flow will still work.

Question: Does Ex2007 UM server include LCS capability?

Answer: No.

Question: In a small org, what roles can sit on same Exchange 2007 server? Must you also have a separate server in DMZ for Edge role?

Answer: Regardless of the size of the business, the Edge role is optional. If implemented it can be the only Exchange role on the server. All of the other roles can be on the same server if you wish or split up if you like as well. The Unified Messaging role is also optional.

Question: Is CAS role required on every e2k7 server or only on the first one in AD site?

Answer: CAS is not required on every Exchange Server.  The requirement is at least one CAS in each AD Site that also has a Mailbox server role.

Question: what about OMA?

Answer: OMA is no longer supported.

Question: For single server setup, should you load the Unified Messaging Role for future expansion, or would you add it later when you actually need it?

Answer: Add it later when it is needed. No need to consume resources if it is not being used.

Question: If we use a custom looking login form for OWA2003, can we get that custom form ported over to the Ex2007 and presented to users logging into their Ex2003 mailboxes?

Answer: Yes, that is possible.

Question: This may have already been covered previously, but I just want to clarify it. Why must Edge role exist alone on a server? Why can't you bundle it along with all the other roles on a single server?

Answer: The Edge Transport server role was developed to be deployed in a DMZ.  For security reasons, this role cannot co-exist on a server with any other Exchange server roles.  This is by design.

Question: The Edge uses it's own database for transient email (dumpster)?

Answer: The Edge Transport is an SMTP smart host (for the most part).  There is no dumpster on the Edge Transport.

Question: is replacing your front-end 2003 servers with a nlb cas recommended before adding a 2007 back-end server?

Answer: Yes, you must implement an Exchange 2007 Client Access server role prior to implementing a Mailbox server role in an environment where you have FE / BE configured.

Question: Hi. I did a migration from 2003 to 2007 and noticed a big difference in the new mail store on 2007 (diff =ca. 20 GB). Is this correct?

Answer: There are a lot of factors that can come into play during a migration.  Keep in mind that any Single Instance Store from your old environment is not carried across.  Also, during the migration, there is a lot of traffic and data copy that takes place.  This can lead to a “puffed up” database as well.  You can perform an offline defrag of the database to see if the size can be shrunk.

***NEW / UPDATE****
Clarification: If you are using a Transition approach to move from Exchange 2000 / 2003 to Exchange 2007 (moving a set of mailboxes within the same Exchange Organization), Single Instance Store (SIS) is indeed maintained, as long as the mailboxes are being moved to the same target database.  Example: Jane, Joe, John and Jack all have mailboxes on DB1.  All four have emails, calendar items, contacts, etc. as well as one common email (that all four have) with a 1 GB attachment.  With SIS taken into account, the total storage in DB1 for these four users equals 5 GB.  If we move these four users to DB2 (same server or different server) within the same Org, the space requirements will still be 5 GB for their mailboxes in DB2.
If you perform a migration of mailboxes between 2 different Exchange Organizations ("forklift"), then SIS is not maintained.
***END of NEW / UPDATE Information****

Question: Will the 32bit eval management code expire when installed on a 32bit OS?

Answer: No.  It is not the Exchange Management Console that expires, but the Server.  The Exchange Management Console gives you the notification if it finds an Exchange Server in the organization that does not have a Product Key entered in.

Question: Are there any issues between MS CRM 3.0 and Exchange 07? Where can I find documents regarding running CRM 3.0 on in an Exchange 07 envir.?

Answer: Yes, there are known issues with MS CRM 3.0 and Exchange 2007 / Outlook 2007.  There will be a patch (from the CRM group) available in the next month or so to address this.

Question: Where can we get the 32bit admin tools for Exchange 2007?

Answer: This would be a part of the 32bit version of Exchange 2007. You can grab this at --  The 32bit tools are here:

Question: How many mailboxes can you move at one time in Ex07?

Answer: no limit, 4 threads at one time

Question: In my huge AD enterprise we have 150 sites. Our E2k3 servers are all in one site. Will we need 150 E2k7 servers (one in each site) to satisfy hub transport role requirements?

Answer: No.  You only need a Hub Transport server role in an AD Site that also has a Mailbox server role.

Question: Just want to be crystal clear. If I have 5 AD sites currently and only one Exchange server in which all mail flows, to upgrade to 2007 and have all those AD Sites have mail flow to them, a hub transport server must be installed in that site?

Answer: You would need to install at least one Hub Transport server role in each AD Site that also has a Mailbox server role.

Question: Okay, I'm still confused. Do you have a link where I can get more information on the Edge role and why it can't co-exist with other roles on a server?

Answer: See the following ---

Question: We have one 2003 native mode site running Exch 2003 native mode. We have a FE BE environment. I ran the Exch Best Practice Analyzer. Do I need to enable link state suppression?

Answer: Even this does not apply to your scenario, then you should be fine.  On the other hand, it can’t hurt either.

Question: If we chose to install Exchange 2007 with all roles on one server (using ISA 2006 in DMZ), how difficult is it to move the Edge role to a new server in the DMZ at a later date?

Answer: You cannot install the edge role with any other role. What you are describing is installing without an Edge Transport, which you can do. Edge Transport is optional and would be installed on its own server in the DMZ when you are ready to do so.

Question: mailbox move is 1-way?

Answer: No.  You can move a mailbox between servers (this applies to 2003 to 2007 as well as 2007 to 2003).

Question: Does OWA 2007 support mail rules management?

Answer: If you are referring to client side configuration of rules from OWA, the answer is no. 

Question: What replaces the inter-org rep tool when both forests are E2K7 native mode

Answer: The Availability Service will be able to query for free / busy across forests.  We no longer replicate free / busy type information using Public Folders.  You can also use the GAL Sync tool to replicate contacts across.

Question: Within which role does the "Antigen" antivirus/spam filtering take place?

Answer: Forefront Security for Exchange can be installed on the Edge Transport, Hub Transport and Mailbox server roles.  Spam filtering is not part of Forefront, but an integral piece to Exchange and is installed by default on the Edge Transport.  The anti-spam agents can also be installed onto the Hub Transport if you don’t plan on using the Edge Transport server role.

Question: OWA binaries are all on the CAS role now not mailbox?

Answer: That is correct.  OWA binaries are not associated with the Client Access server role.

Question: what about SBS with Exchange 2007? when is this expected?

Answer: At this time there is no plane to update SBS 2003 with Exchange 2007. Since E2007 is 64bit only and there is no 64 bit version of SBS, you can expect the next version of SBS to have E2007 support. There will be a 64bit version of the next SBS. Please see the following for (a little) more information ---

Question: Am I correct in saying the Edge Role goes on a server that is NOT part of the domain?

Answer: The Edge Transport server role is installed onto a server that is NOT a member of the production AD Domain.  It can be a member of an AD Domain such as a DMZ domain for management purposes.

Question: after the user mailbox has been moved to E2k7, must one wait for RUS (and whatever else needed) to complete b4 he can access his m/b on the new E27k m/b server?

Answer: No, the mailbox will be available immediately after the move completes.

Question: Do you know where ADAM keeps contact information replicated from AD in EDGE server?

Answer: For more information on ADAM, please see the following ---  Keep in mind that the structure in AD for user object storage will be “duplicated” in ADAM so the structure will be the same.

Question: If you do not have an Edge server, can you install "antigen" on one of the other server roles? if so, which one?

Answer: Yes.  You can install Anti-Virus engines on the Edge Transport, Hub Transport and Mailbox server roles depending on the Anti-Virus application in use.  This is true for Forefront Security for Exchange.

Question: Are the 32-bit management tools included with the EX2K7 DVD or should I download the 32-bit version?

Answer: You can download the 32 bit tools for Exchange 2007 from here as well ---

Question: I might have missed this..we should ONLY move mailboxes from 2003 to 2007 using the Exch 2007 management tool only, right? I should NOT move the mailboxes using the 2003 management tools.

Answer: That is correct.

Question: would a typical install create a new org?

Answer: If one does not exist, yes.

Question: you need ESM to manage coexistance routing groups?

Answer: You will continue to use the Exchange System Manager (Exchange 2000 / 2003 tool) to manage the Exchange 2000 / 2003 environment.

Question: So you can no longer move mailbox from within AD U&C ?.

Answer: In relation to Exchange 2007 administration, that is correct.

Question: When transitioning to a new exchange 2007 server, does the domain name have to be the same as the exchange 2003 server or can you use a different domain name or perhaps a sub-domain?

Answer: When transitioning to Exchange 2007 from Exchange 2000 / 2003, you do not implement a new AD Domain.  If you are referring to the SMTP Domain, most people usually keep the same SMTP Domain unless you are also “transitioning” to a new domain space.

Question: When we do transition and are ready to decommision the old Exchange 2003 servers, you said that we can delete the "old" routing groups and their connectors and unistall Exchange 2003 servers. What can we do with the "old Admin Groups? Should we leave them in the organization or move resources to the "Exch 2007 AG" and delete them?

Answer: You shouldn't have any resources left in the "old" admin groups so you can delete them as well.

Question: Can you use vbscript to run cmdlet's ?

Answer: Sure.

Question: Where do folders etc. move?

Answer: I don’t fully understand this question but will answer it as best as I can.  If you are referring to folders within a user’s mailbox, they are moved as part of the mailbox.  If you are referring to Public Folders, then these are “moved” only if you choose to move them or replicate them.

Question: if you plan on using CCR, should you install both/all members of the CCR cluster first before migrating mailboxes from Exch2003, or should you wait until the mailboxes are all moved, or does it matter?

Answer: Keep in mind that a CCR cluster is configured at the point of installation.  If you wish to use CCR, then you will need to install the Active and Passive nodes before moving mailboxes to it.  You cannot take an existing Mailbox server and “change” it to a CCR node.

Question: Does OL2007 revert to PF for FB in Ex2k3 environments?

Answer: Yes, Outlook 2007 will work just fine in an Exchange 2003 environment and adhere to the "old" connection requirements - in this case, Public Folders.

Question: Do we need to plan LCS migration along with the Ex 2007, as i believe UM Servers will cover this functionality?

Answer: The current version of LCS 2005 SP1 works fine along side Exchange 2007.  Remember that LCS 2005 provides presence and Instant Messaging.  Exchange UM provides voicemail and inbound fax.  These are two different items.

Question: Where are the past webcast powerpoint presentations kept?

Answer: you can go to the same link for the webcast and download the webcast for later viewing

Question: Are there 64bit tools included on the DVD that I could install on 64bit XP?

Answer: Yes.  Make sure you on are SP2 and have all the necessary pre-requirements.

Question: Can I network-load-balance 2 servers, each having CAS+hub+mbx roles?

Answer: The Mailbox role is not supported in that configuration. You can cluster the Mailbox Role and then load balance another set of servers with the CAS and HT.

Question: When a users’ mailbox is disconnect and then connected to another user, why do you have to manually give full access to the mailbox for the user you are connecting?

Answer: Because the "connecting" process does not automatically grant permissions to the mailbox. Remember that for security, only the user that owns the mailbox has access rights.

Question: The Exchange 2007 help says that when you do a single forest transition, you do not have to replicate system folders from old servers to Exch 2007. How would Free/Busy work then as LegacyExchangeDN for users that have their mailboxes moved does not change and they still point to the old Admin Group.

Answer: If you are planning to use Outlook 2007, then you will have no issues. If you are using Outlook 2003 or older, then you will need to replicate System Folders. When installing Exchange 2007, there was a question that asked about the use of Outlook 2003 (or older) or Entourage. You would need to check that as a "Yes" in order for the Public Folder structure to be created and such on the Exchange 2007 environment.

Question: Are there still eseutil and isinteg tools in e2k7?

Answer: Yes. You would run these from the Exchange Management Shell.

Question: 64bit hardware can be either Intel or AMD correct?

Answer: Yes.

Question: How should be plan to move our e2k3 resource mailboxes that are registered with the Auto Accept Agent?

Answer: You would move them to Exchange 2007 as normal. You would need to enable all of them with Auto Accept (no need for the agent now) using the Exchange Management Shell.

Question: If you cannot use the AD U&C, what tool can you use to provide a "restictive" way to administer mailbox (moves, updates, etc)?

Answer: You would delegate permissions and then give the person the Exchange Management Console with only the Recipient node exposed.
