Exchange Server 2007 Series (Part 4 of 24) Questions and Answers Log (1-31-07) 

Question: Is there any order when I set up exchange 2007 server role from the scratch?

Answer: When installing from scratch (not Transition), you can install any of the following three roles in any order: Mailbox, Hub Transport and Client Access.  Until you have all three roles, you will not have a fully functional Exchange 2007 environment.  You cannot install the Unified Messaging role until you have a Mailbox role in place.

Question: We have Ex5.5 under the NT domain for currently usage. I will install Ex2007 under the AD domain for testing before getting rid of 5.5. How can I make sure all email goes to the 5.5 instead of Ex2007 (only one domain name)? and how can I change it to the Ex2007 after retiring the 5.5?

Answer: First, if you deploy Exchange 2007 in a test environment, you should not try to just move it into production.  Testing is just that, testing.  See for details on moving from Exchange 5.5 to Exchange 2007.

Question: is it possible to install the exchange management console on a 32bit XP or Vista Workstation

Answer: See for details on this.

Question: Will there be any discussion of installing/running exchange in a VM or some type of virutallization?

Answer: I don't know if Harold will discuss that, but you can also find information on Exchange 2007 and virtualization at

Question: Scott Schnoll’s article on Virtualization is outdated as VM now supports 64Bit VM's. Do you have any other blogs or sources?

Answer: Actually, it's not. Microsoft Virtual PC as well as Virtual Server only support 32 bit VMs.  Our support policy remains unchanged with respect to virtualization.

Question: What kind of server role to setup for a public Internet access OWA in a secure manner?

Answer:  Here’s a specific link:

Question: Do I still need a script to enable Anti-Spam (IMF) on a single Ex2007 acting as Hub, Mailbox and CAS roles?

Answer: Yes. See for details on how to enable anti-spam functionality on the Hub Transport server.

Question: I read that the smpt and nntp services cannot be running if you are running the hub transport role. Then how can you install all the roles on one box? (except for edge transport, of course)

Answer: You cannot have IIS SMTP or NNTP installed on any Exchange server role. These features are no longer needed or used by Exchange 2007. In Exchange 2007, NNTP has been removed completely, and instead of IIS SMTP, Exchange 2007 now uses its own new, completely re-written SMTP stack.

Question: Speaking of supported clients. Is there a client for the Macintosh?

Answer: Entourage and Outlook Web Access can be used on the Mac platform. Also, so can many POP3 and IMAP4 applications for the Mac.

Question: Can Ex2007 co-exist with Ex2000 for IM purpose only without single Ex2003 in the Exchange Org?

Answer: Yes; however, you will get a much better experiencing using Exchange 2007 and Live Communications Server (with Office Communicator on the client).

Question: Where do I find a link for AD Prep (forrest, domain, shcema)?

Answer:  Also, look here:

Question: A single server scenario is still supported, correct? What about multi-ste, single server scenario with high speed connectivity? One server supported?

Answer: Single Server is supported if you only need the Mailbox, Hub Transport, Client Access or Unified Messaging roles.  If you need to cluster the Mailbox role or if you want to deploy an Edge Transport, then you will need more than one server.

Question: Should I run the setup /prepareAD even I install Exchange 2007 using the wizard or the wizard performs this step for me?

Answer: That is up to you. If you don't run it separately, then installing the first Exchange server will perform that task for you automatically (provided you have permissions to the schema). But, you might find reasons to run the step separately, such as in the case of when you have a large, distributed environment, and you want to perform the task off-hours to minimize the impact of schema change replication throughout your directory servers.

Question: When will Microsoft release a Small business server version with Exchange 2007?

Answer: Sometime after Windows Longhorn Server releases.

Question: coexistence E2003 SP2 is required?

Answer: When Transitioning from Exchange 2003 to Exchange 2007, you do need to have SP2 on your Exchange 2003 servers.

Question: ok in x86 whe need a fix for .net framework in X64 to ?

Answer: There are a few fixes that are required after the base .Net 2.0 components are installed.

Question: Why does the Edge Server need to be on a separate DC?

Answer: Edge Transport server does not need to be on a separate DC. In fact, it should not be installed on a DC. And even if it is installed on a DC, it won't use Active Directory for its Exchange functions. It will still use its own local instance of ADAM. Edge cannot be a member server of an internal AD domain (that is, an AD domain on your internal corporate network); however, it can be a member server in an extranet forest (an AD forest located in your perimeter network) if you so desire. One benefit to having it be a member server in an extranet/perimeter network domain is that you can manage it using Group Policy. This is useful if you have a large Org with several Edge servers to manage.

Question: When installing Ex2007, SMTP service will be removed automatically or I have to disable it before the Ex2007 installation?

Answer: No, it will not be removed. You need to uninstall it (not just disable it) prior to installing Exchange 2007.

Question: I intend on placng the edge server within my proteted network..So it will have access to my DC?

Answer: Edge should not have access to internal servers other than the Hub Transport servers to which it is subscribed. It will not use your internal AD forest, domains, or DCs for Exchange, as Edge is specifically designed to use only ADAM. Edge cannot be a member server of an internal AD domain (that is, an AD domain on your internal corporate network); however, it can be a member server in an extranet forest (an AD forest located in your perimeter network) if you so desire. One benefit to having it be a member server in an extranet/perimeter network domain is that you can manage it using Group Policy. This is useful if you have a large Org with several Edge servers to manage.

Question: what is the MS recommended best practice with the prepare switches, do legacyexchangepermissions first?

Answer: If you want to deploy schema extensions and prepare AD with necessary permissions prior to deploying your first Exchange 2007 server, then you would run with the necessary prepare switches at the appropriate time.  There is no requirement to do this first (provided you have the necessary permissions to AD).

Question: How can I remove the old Exchange 55

Answer: The easiest way is to migrate to exchange 2003 and then move to 2007 in a tiered deployment.

Question: Since Outlook 2000 does not work with E2007, do the purchase of Exchange CALs automatically entitle me to upgrades?

Answer: First, Outlook 2000 will work with Exchange 2007; we just don’t officially support Outlook 2000 anymore.  Second, we no longer provide an Outlook CAL with the Exchange 2007 CAL.

Question: Is there a step-by-step instruction list to installing EX2007 on the tech help site?

Answer: The Deployment Guides and checklists are good. See as a starting point.

Question: Do you have to run all these switches before the install or does the GUI install do it? Note: We already have AD running.

Answer: Either. Depends on the size of your org and if you want to do the schema updates at a particular time.

Question: Should the CA server role be on a separate server for security reasons since users will be accessing this server for OWA, etc?

Answer: Clients can access the CAS server using Outlook Web Access (and perhaps using other client access methods) from the Internet, but that does not mean it’s not secure. CAS must be deployed on the internal network; we do not support CAS servers in a perimeter network. And we recommend that you deploy a robust firewall to publish OWA and other client access protocols that you need. ISA 2006 is great for this. Using ISA, you publish TCP port 443 (HTTPS), and clients connect using HTTP secured by SSL through a single port that is opened on your firewall. See for more information on managing client access security.

Question: IS Ex 2K7 pre-install supported?

Answer: That depends on how the install is done. In most cases, pre-install won't be an option because Exchange requires access to AD during setup..

Question: what is the requirement for the edge transport reqirement again in regards to DNS settings

Answer: See for DNS advice.

Question: Will we be able to run the Management Tools on Windows Vista?

Answer: Support for the Management Tools on Vista is planned for Service Pack 1 for Exchange 2007.

Question: Is the mailbox role the only role that is available for clustering?

Answer: Yes.

Question: Is Outlook 2002 SP3 essentially the same as Outlook 2003 from the Exchange 2007 perspective?

Answer: Outlook 2002 is supported for Exchange.

Question: my exchg 2003 servers are not 64bits, how do i upgrade to exchg 2007?

Answer: Exchange Server 2007 is only supported on 64bit hardware.  You will need to acquire a new x64 bit server and install Exchange 2007 onto that server.

Question: Can CCR be configured in a round robin format. If I have 5 servers, can I have one server accept log shipping from another server while shipping it's logs to another server?

Answer: No, this is not possible.

Question: How about Management Tools on Windows XP? Is that supported?

Answer: Yes. Please see for details.

Question: is it possible to script the installs via the powershell and is it supported?

Answer: Yes

Question: I hate to bring this up one more time but I have to be certain in order to advise a client. Microsoft is not supporting as of now Exchange 2007 in a virtual environment.

Answer: This is correct.

Question: Where did he get that cool background? 🙂


Question: If I select hub transport role, I can't choose cluster option?

Answer: Correct. Only the Mailbox server role can be clustered.

Question: Roughly when is Exchange 2007 SP1 expected?

Answer: There is no official ETA on Exchange 2007 SP1 at this point.  I would predict it will be out before the end of this calendar year, but am hoping it will be sooner than December 31st.  [Harold]

Question: Why is Exchange 2007 only supported on 32 bit hardware? Why is there not going to be a 32bit version released?

Answer: The decision was made early on as there are limitations to a 32bit architecture.  Some of these include I/O performance which would cripple the server when introducing larger mailboxes. 64-bit improves I/O performance by 70%. Also 32bit is memory limited to 4GB. 64-bit is required for scalability.

Question: Has any cluster product been certified with 2007? ie. double take, neverfail?

Answer: No; we do not certify applications for Exchange (and we never have).

Question: How could we cluster or load balence Hub server ?

Answer: No need to do anything special. Just deploy more than one Hub Transport server in each AD site containing a Mailbox server. Resiliency is built into the Hub Transport server architecture. See for more information.

Question: What about exchange 2003 service packs? Is SP1 enough? I have a space limitation.

Answer: To coexist with Exchange 2003, you need to be at SP2 or higher:

Question: If we choose to select outlook 2007 support, (no OL2003 or earlier) can we revert back if we later find we need to suport OL2003 clients, or can we setup a separate server for just those legacy clients?

Answer: yes this is possible.  You would need to configure the Public Folders manually if it wasn’t already done.

Question: Edge can route for 2 distinct Exchange orgs?

Answer: No, this is not supported.

Question: Clustering is not supported when you choose hub transport role

Answer: That is correct; Hub Transport and Client Access would need to be installed on a separate server. No need to do anything special for Hub. Just deploy more than one Hub Transport server in each AD site containing a Mailbox server (for redundancy). Resiliency is built into the Hub Transport server architecture. CAS can use NLB. See for more information on server role-based high availability.

Question: We want to use CCR. I read that you shouldn't use CCR on the first mailbox role that is being deployed into a mixed environment because of public folders. Is this information correct? Or, is it ok for me to setup the first 2007 mailbox role with CCR?

Answer: I don't know where you read that, but that is not correct. But, please do see for details on public folders and CCR.

Question: By not supporting public folders in 2007, what's the transition path? SharePoint?

Answer: We support public folders in Exchange 2007. And it’s likely that public folders will also be present in the next version of Exchange after Exchange 2007. But our long-term strategy does remain SharePoint and Office.

Question: Clustering--- so if MB server can only be clustered, where's the redundancy if I lose the box I have the HT, MB, and CAS installed on one box?

Answer: You can get data redundancy using Local Continuous Replication. Beyond that, you would need multiple servers to provide high availability for Hub and CAS. See for more information on server role-based high availability.

Question: I thought that /prepareAD will be run automatically when you install a first e2k7 server inot the org?

Answer: It will be, if Setup detects that it has not yet been run and provided you have permissions to do so.

Question: Do we still have to upgrade all of our E2K3 front-end servers first? If so, how do we introduce a new E2K7 client access server with the E2K3 front-end server still going?

Answer: First you won’t be able to "upgrade" in place because of the 64bit OS and Hardware requirements. The best is to introduce a new server in the org and then move the responsibilities and then phase out the old box.

Question: CCR will not allow support for PFs that use replication to other PF dbs?

Answer: More precisely, we don't support lossy failovers in that scenario. The details are documented at

Question: What is CCR?

Answer: Cluster continuous replication. See for more information on CCR.

Question: does maint mode take server offline while performing

Answer: No.

Question: It hasn't been ask but! Ex 2k3 on Server 64bit, upgrade? hardware is there, has any one seen this?

Answer: That is not supported. Exchange 2003 can only be run using the 32-bit version of Windows Server.

Question: Are there any websites or docs on how to migrate from Novell GroupWise 6.5 to Exchange 2007?

Answer: Microsoft does not have any tools at this time.  There are third party tools available to assist.  Take a look at the following site from one of our Exchange MVPs:

Question: can roles be installed from gui? and is it better to do that via console?

Answer: You can use either a GUI or command-line to install Exchange.

Question: will e2k7 owa support accessing e2k3 backend servers?

Answer: Yes. The client experience is based on their mailbox location. If the mailbox location is Exchange 2007, the CAS will deliver the Exchange 2007 client; if the mailbox location is Exchange 2003, CAS will deliver the Exchange 2003 client.

Question: do you have a step-by-step instruction for migrating from exchange 2003 to exchange 2007?


Question: For the install hotfix check, what internet ports does it need access to?

Answer: None (to perform the check). It checks the local machine for the pre-reqs and updates that are required. That said, Setup will contact the Web site to see if any updates are available for the Setup engine (similar to ExBPA updates). This way, if new pre-reqs are added, or if they change, we can make a change to the config file, post it to, and then Setup can download it and use it.  To download the update(s), you will need access to the Internet.

Question: has the team released further tools that are similar to EXBPA and help in the deployment of E2007?

Answer: Yes, there are several tools inside the Toolbox that are included with Exchange 2007.

Question: e2k3 owa will not support e2k7 backend servers correct?

Answer: The client experience is based on their mailbox location. If the mailbox location is Exchange 2007, the CAS will deliver the Exchange 2007 client; if the mailbox location is Exchange 2003, CAS will deliver the Exchange 2003 client.

Question: What was he hitting to go thru the commands quickly?

Answer: The TAB key.

Question: Any word on when the Notes connector will be available?

Answer: I don’t have an ETA at this point, but I’m expecting it soon.  [Harold]

Question: what is not included in OWA Lights?

Answer: Please see for this information.

Question: if my exchg 2003 hardware is not on 64bit, can i upgrade using the transition method or the migration method?

Answer: You can perform a transition. Most existing Exchange 2000/2003 organizations will perform a transition.

Question: is there any way to licence the evaluation version?

Answer: For 64-bit, yes. That is how you move from the trial version to the purchased, retail version.

Question: If I have a front end server running E2K3 and I move my mailbox to e2k7 server, will I still be able to access it via E2K3 fron end server?

Answer: No, that is not supported.  However, you can access an E2K3 mailbox from an Exchange 2007 CAS.

Question: what upgrade method would you in an Exchange 2003 environment where the Exchange 2003 servers will be later decommissioned

Answer: Transition.

Question: you need to be a member of view only admin to read all this stuff on Exchange in AD?

Answer: Yes.

Question: curses! 🙂 i wanted to run the et role in a vm and not have to dedicate a x64 machine to it

Answer: You can run the 32-bit version in a VM for non-production use (in fact, we even offer a demo VHD from the Microsoft Download Center that also includes Live Communications Server). See for additional information.

Question: do you have the ability to restore individual mailboxes in exchange 2007?

Answer: If you use a backup program that supports brick level backup.  NTBackup does not support this.

Question: If you have Outlook 2007 installed on all clients in an Exchange 2003 environment do you still need to select the option for public folders during the install?

Answer: If you have only Outlook 2007 as your client, and you have no need for Public Folders, then you can specify that there are no legacy clients during Setup, and a public folder database will not be created automatically for you.

Question: Is Harold using EX2K7 32BIT with VIRTUAL PC 2K7

Answer: Yes, although normally he uses Virtual Server 2005 R2

Question: Is the Toolbox downloadable separately and can it be installed prior to Exchange install?

Answer: The Toolbox is integrated into the Exchange Management Console, but you can download that separately for use on your 32-bit desktop from  If you have a 64-bit desktop, you can run Exchange Setup and install only the Management Tools.

Question: Do you loos Single Instance Message when you transition to exchange 2007

Answer: SIS is an interesting thing. When people talking about breaking SIS sometimes they mean different things. Generally, the way it works with SIS is: 1. If you use ExMerge or some other tool to export messages out of the system (for example, into a PST file) and then from that PST you import the messages, then SIS will break. 2. If you use the Move-Mailbox process to move data between mailbox databases, then SIS will be preserved. You can use the performance counter called Single Instance Ratio, which is under the MSExchangeIS Mailbox performance object to see what the SIS ratio is for each storage group, or in total for the Mailbox server. Most of the organizations I’ve seen have SIS ratios in the 1:1.5 or 1:2 area. But each org is different. Some more information can be found at

Question: Does Exchange 2007 offer any new features for company mergers and divestitures?

Answer: Yes, being able to merge and separate orgs. These features are there.

Question: Is there a Management Agent template to deploy Exchange in a dedicated forest using IIFP or MIIS ?

Answer: Unfortunately, that does not exist today. I'm not aware of any plans for this either, but that does not mean there aren't any in place.

Question: When performing via the command line, when entering the Org name via "/organizationname:" Is the Org name itself case sensitive? It always has been in the past...

Answer: Yes, it is.

Question: what traffic/services use RPC and what use SMTP in E07 native and mixed with E03?

Answer: The Hub Transport uses SMTP for email delivery. UM and CAS uses Exchange RPC to communicate with the Mailbox server.

Question: We have 2 way trusts with an external domain which houses their own AD. The active account is in their domain. The disabled AD account with the mailbox enabled is in our domain. Does the external domain need a GC or DC with Server 2003 sp1?

Answer: No, there is no requirement for the external organization to have Server 2003 SP1 on their DC / GCs since the Exchange items are in your AD. I would consider this a Resource Forest topology.

Question: one last question, if I may. Why release a 32bit trial version if 64bit is the only one going to be released?

Answer: The 32 bit trial version is for companies to run in a lab on "older" hardware or in a virtual machine environment, for demonstration purposes (like I am doing via Virtual PC - which is a 32 bit emulated environment) and for training purposes for the same hardware type reasons as the first two. The 64 bit version is what we support in production deployments.

Question: Is there any issue if some DC is W2K3 SP1 and others are R2 when Ex2007 is installed?

Answer: Not at all. Remember, R2 already has SP1. I would recommend going with R2 (personally).

Question: How can you add the Powershell cmdlets for Exchange to a non-Exchange server (or XP) so you can use them?

Answer: For Windows XP Professional SP2, you will need to install the three pre-requisites (.Net 2.0, MMC 3.0 and PowerShell 1.0) then install the Exchange 2007 Management tools from the Exchange DVD. If you are running 32 bit version of Windows XP, then use the 32 Bit evaluation copy of Exchange Server 2007 to install the management tools (this is a supported use of the 32 bit code).

Question: Is forefront already out?

Answer: Yes!!!

Question: E07 requires 64 bit h/w..can one install/setup E07 in 32 bit h/w in lab? if yes, would I have to do anything different?

Answer: That is correct. The only "difference" is related to versions of PowerShell (32 bit versus 64 bit) and things like that. Also, you will not be able to truly test the UM piece since you cannot connect the necessary telephony hardware to a Virtual Machine correctly. If you are interested in testing UM, then you will need to install that role onto a 64 bit box even in your lab.

Question: Does setup /PrepareDomain have to be run in a child domain that has an Exchange 2003 server that will coexist with an Exchange 2007 server in the root domain where setup /PrepareAD has been run?

Answer: Only if you plan on installing an Exchange Server 2007 server in that Domain.

Question: Would E07 mailbox use RPC to rout mail to E07 mailbox and E03 ...would Edge use SMTP to rout to Hub?

Answer: Remember, the Hub Transport Server is responsible for routing mail, so the first part of your question is a mute point. As for Edge, it does use SMTP for routing to the Hub Transport.

Question: I understand E07 native can't use PF, uses mixed mode, it can use both, right?

Answer: That is totally incorrect!!! Public Folders are 100% supported in Exchange 2007. We just no longer Require Public Folders like we did in previous versions. So if you don't want to use them, you can get rid of them provided you are not using any Outlook 2003 or older clients or Entourage.

Question: what protocol mailbox server uses to send mails to Hub for routing?

Answer: The different server roles use Exchange RPC for communications between each other (CAS to Mailbox, UM to Mailbox, etc.).  The Hub Transport uses SMTP for email delivery.

Question: our ex2003 server is on our perimeter network, is there documentation on how to introduce an ISA 2006 server and move the ex2003 server (FE and BE) to the internal network in preparation for a transition to ex2007?

Answer: Here’s information on deploying ISA 2006 with Exchange 2007:  In terms of moving an Exchange 2003 FE out of the DMZ into the Corporate network, I don’t really see any official documentation on that.  You would need to move the FE back onto your internal network and reset all the IP settings.  Once you confirm it is communicating correctly, you will want to publish the client access components via ISA 2006 (which you should already have up and ready to go as well).

Question: In setting up RPC over HTTPS in Exchange 2003 it was easier to set it up with a BE and FE Exchange Server, is that true with Exchange 2007 or is it easier to setup securely with all roles on one Ex07 server?

Answer: In Exchange Server 2007, it doesn't matter anymore since we did make this easier.
