Exchange Server 2007 Webcast Series (Part 1 of 24) Q&A Log

Whew!!  The first part of 24 in the Exchange Server 2007 webcast series is now complete.  During the webcast, I had a few challenges (power surges that dropped my phone call and killed my Internet access) that caused a few interruptions.  Thank goodness I had a cell phone and the Verizon EVDO connection so that I could complete the webcast.  Thanks to all for your patience and understanding during these challenges!!!!!  I also want to thank my team mates, Chris Avis, John Weston and Bryan Von Axelson as well as Scott Schnoll from the Exchange team for helping out with questions during the webcast!!

Please understand that this was part 1 of 24 so there is still a lot of information that I have not even begun to cover yet.  If you will be patient, I promise I will cover off on quite a bit of information for Exchange Server 2007!!

There were quite a few attendees online and boy were there a lot of questions.  I have done my best to edit the Q&A log so that it is readable.  I know there are duplicate questions (from different attendees) despite the fact that I did my best to eliminate them.  I am posting the edited Q&A log below.  If I missed something, please let me know.  Thanks.

Answer: Yes, you will be able to access the on demand of this webcast, within 24 hrs from -

Question: We are in one Routing group now; in 2007 will we need to create connectors between AD sites?

Answer: The Exchange 2007 Hub Transport Role manages all of this automatically.  You will need to have at least one Hub Transport Role in every AD site that contains an Exchange 2007 Mailbox Role.

Question: Can we not chat with other meeting participants?

Answer: Sorry, but that is not possible.

Question: Why can’t I register for all 24 webcasts in this series at once? If I choose to register for the SBSC 70 - 282 Exam Prep series at (<>), and choose “Register Now” it takes me to <>, shows all the webcasts in the series registers me with one click.

Answer: We simply have not established a process for doing a bulk registration for this webcast series. We are looking into this and will have an answer soon.

Question: doesn’t the edge server role HAVE to sit on a different server? Do you HAVE to use edge server role to connect to the Internet?

Answer: The Exchange Edge Server Role CANNOT co-exist with any other Exchange role. You don't have to have an Edge Server to connect to the Internet, but it is recommended.

Question: will Harold have a session and/or labs concentrating on implementing anti-spam (and possibly AV) functionality?

Answer: Yes, I will.  Anti-Spam:  Anti-Virus: .

Question: If we are not yet ready to upgrade all Exchange servers to 2007, can we run with 2007 client access servers and Exchange 2003 back-end servers?

Answer: Yes.  User’s whose mailbox resides on an Exchange 2003 Back-End server will have the Exchange 2003 OWA interface.  If you have existing Exchange 2003 Front-End servers, you should introduce Exchange 2007 CAS servers first.

Question: so, you can deliver and receive mail over the internet WITHOUT an Edge Server?

Answer: Yes, absolutely.

Question: compliance: are there any restrictions to the use of such E2k7 features to enforce compliance outside of the US, particularly EMEA? Can you point me to authoritative references to this? Thanks

Answer: I cannot speak to any restrictions on the use of Exchange 2007 Features in Countries outside of the US. You are better suited speaking to a local Microsoft Sales Office about feature restrictions in your area.

Question: are there MS exams for Exchange 2007?

Answer: The Exchange Server 2007 exams have not been released yet.  They are forthcoming, but I do not have a timeframe.

Question: Can we integrate Exchange 2007 environment into an existing 2003 Org?

Answer: Yes that is an option in the Transition (I call this an Exchange Organization upgrade).  Please see:

Question: Do we need a 64 bit machine to install just the edge server alone?

Answer: Yes, Exchange Server 2007 is 64-bits only – even the Edge Server Role.

Question: Where did STM files go in 2k7? Are the STM functions wrapped into the EDB files?

Answer: STM files are gone in Exchange 2007. We still use JET as the database engine in 2007 and preserve the EDB file format.

Question: Will the PowerPoint files be made available? I prefer PPT above PDF

Answer: Within 48 hours after the webcast, you should receive an email with links to download the on-demand viewing of this webcast as well as a link to download the PowerPoint file.

Question: The edge server role is designed to act as more or less a border message hygiene server, correct?

Answer: Yes as well as security for SMTP connections.

Question: change from exchange 2003 to exchange 2007 will we need to upgrade the hardware to 64bit?

Answer: Yes. Exchange 2007 is 64bit only.  Also, keep in mind that you cannot perform an in-place upgrade of the Exchange 2003 Server to Exchange 2007.

Question: So the HTML message format is all handled in the EDB file, great! So is there a conversion location anymore (the "working" directory) that takes care of Rich-Test to HTML conversion (and back again), or is this handled in another way?

Answer: Everything is stored in the EDB file.  The STM file no longer exists.

Question: we're going to build Exchange2007 from scratch in our four locations, all database and mailbox servers will be in our Datacenter. What do you recommend? We have to build exchange server on each of our location or only in datacenter. Thanks.

Answer: You will have to evaluate the topology that suits your business needs. You can get information on Exchange 2007 Design at ---

Question: Will moving mailboxes from Exchange 2003 to Exchange 2007 preserve Single Instance Storage?

Answer: Yes, it will.

Question: does ex2007 enterprise edition run on win2003 Ent edn?

Answer:  Yes, so long as it is the 64 bit version of Windows 2003 Enterprise Edition.

Question: Is there a new version of Windows Mobile due to be released with Exchange 2007?

Answer: Windows Mobile (if you are referring to the OS on Phones and PDA's) is a separate product from Exchange and has a stand-alone development cycle. There is no specific tie to Exchange release schedules.  With that said, there is another version of Windows Mobile due out that will take advantage of new features in Exchange Server 2007.  The availability date has not been announced.

Question: Are you still limited to 1 org per forest?

Answer: Yes.

Question: In the Trial Versions of Exchange 2007 there was a 32-bit version, you have removed that option for retail?

Answer: Yes, the 32 bit version of Exchange 2007 is for testing, demo and training only, not production the production version will only be 64 bit

Question: If we get our AD administrators (separate group from our Exchange admin group) to run the adprep (schema mods) for Exchange 2007, well in advance of our deploying the first Exchange 2007 server, will this cause any problems in our existing fully 2003 environment? Any changes in how we do things pre-first-2007 server in this situation?

Answer: There are no known issues with implementing the Schema Extensions in advance of the Exchange 2007 deployment.  I know organizations that perform these types of tasks 6 months or more in advance. You can read up on the specific processes here --

Question: IF VMWARE ESX Server 3.0.1 supports 64 bit client VMs, can you load it into a win2k3 64bit vm?

Answer: Technically - yes. However, currently, we do not officially support Exchange Server 20007 in a Virtual Machine environment.

Question: Must PrepareForest be run from a 64bit schema master?

Answer: No, you can use the 32 bit demo version of Exchange Server 2007 for this step (it is officially supported).

Question: When will virtual server support Exchange 2007 (64 bit) running as a guest?

Answer: Longhorn Server will have new Virtualization technology (Hypervisor) that will support 64 bit guests.  However, there is no guarantee that we will “officially” support Exchange Server 2007 in a Virtual Machine environment.

Question: Harold was referring to labcasts, where can I find more information on that?


Question: I'm not having power outages...he really needs to move somewhere else in Phoenix.

Answer: No thank you.  I like the area of town I live in.

Question: Tell Harold to stop using his hair dryer while he's doing the presentation.

Answer: But my hair was wet and it’s cold over here!  J

Question: What is the best place to install my first Hub server when I have a star-topology network? I assume it would be in the center rather than in a branch?

Answer: You will need to have at least one Hub Transport per AD site that has an Exchange 2007 Mailbox Server role.

Question: What can Managed E-mail Folders do in Ex 2007 Enterprise Edition? (<>)

Answer: managed Folders are Administrator created folders that can be managed entirely by the admin. You can set expirations, move messages, archive messages, etc.

Question: Can you install the Hub Transport role on all your Win2k3 Domain Controllers, What's your your recommendation?

Answer: The general rule of thumb is that a Domain Controller should not have other services or applications loaded to it. So my recommendation would be to NOT install any of the Exchange roles to a DC.

Question: Are there any good alternatives to CCR for failover exchange servers? We can't afford 2 cluster nodes, then 1 or 2 add'l hub transport servers (+ licensing costs). Thanks.

Answer: There are other alternatives to CCR from our partner community.  I can’t say these alternatives will be cheaper or more expensive, but you can find a list of partners at:

Question: how many hub transport server will be need in multiple site?

Answer Privately: You will need a minimum of one Hub Transport per AD site in which a Mailbox Server exists.  For redundancy, you may want more.

Question: Does hub-to-hub communication do so using SMTP?

Answer: Yes, it does.

Question: Am I right in saying for redundancy purposes you would need a minimum of 2 Mailbox role, 2 Hub Tranports role, 2 Client Access role and 2 Edge Transport role. Thats a total of 8 physical servers.

Answer: If you want to have redundancy on each Role, you would need a minimum of 4 physical servers.  2 for the Mailbox Role (using CCR) and 2 for the CAS and Hub Transport (can be installed onto same server).

Question: Does DSAccess still exist as a component in E2K7? If not, what handles the actual DS interaction?

Answer: Yes, DSAccess still exists.

Question: To use the Edge Transport you have to have Enterprise CAL's right?

Answer: No, that is not required.  It all depends on the feature set you wish to take advantage of.

Question: do you need to have client access server role on mailbox server anymore or do you just need the one cas server (i.e. is the front end back end topology totally gone for 2007)

Answer: The CAS role can be installed onto the same server as the Mailbox Server or onto a separate server.  Either way, you will need to have at least one CAS role to have a fully functional Exchange 2007 environment.

Question: do we need edge transport server?

Answer: No. The Edge Role is an optional role.

Question: What routing protocol is used in the hub role for route discovery and least cost path?

Answer: The Hub Transport queries AD for this information.

Question: Will the Hub Transport support anti-virus functionality? Right now, hubs don't do AV 'cause AV operates at the mailbox and not at the MTA level. Thanks.

Answer: That is not correct.  In Exchange Server 2007, we still support VSAPI, but the recommended AV method is to use an AV agent that integrates with the Hub Transport Role and Edge Server Role:

Question: what server OS software do you use for the edge server?

Answer: All Exchange 2007 roles require Windows Server 2003 SP1 (or higher) 64 bit edition for use in production.

Question: Is the Hub transport role established on only 1 server?

Answer: no, you can install multiple Hub Transports. You need at least one Hub Transport per AD site with an Exchange 2007 Mailbox Server.

Question: can the connector costs be manually adjusted on the Hub Transport servers

Answer: Yes.  You can use the Set-AdSiteLink cmdlet from the Exchange Command Shell to perform this task.

Question: Does the UM role come with faxing capabilities out of the box?

Answer: Yes for inbound only. If you need outbound faxing, you will need to go with one of our partner solutions.

Question: How does licensing work for splitting up the roles? ie, if I split up 3 of the roles across 3 servers, would I have to pay for 3 Exchange "licenses"? Or do you pay for those licenses (per role) regardless of how many servers you use?

Answer: You will need to license each physical server that you install Exchange Server 2007 onto.

Question: Can you add Edge transport server, UM server later afterwards

Answer: Yes. You can always add roles later as you need them in your business.

Question: so we can add on edge transport server in the future as long as we need it?

Answer: Yes.

Question: 32 bit version is only to be used for testing and not production; it is not supported for production

Answer: Correct.

Question: I think that something should be mentioned that you can run the IMF on the hub transport role as well, this is not very well known

Answer: This is correct.  You need to install the agents on to the Hub Transport Server.

Question: in a single server role do you still need to setup an edge server?

Answer: no, the Edge Server Role is optional, but highly recommended.

Question: What licensing is required to add the Unified messaging role?

Answer: You will of course need to install the Exchange UM role (an additional server license if installed onto a separate server from existing Exchange servers) and you will need the Exchange Enterprise CAL for each user that will use the features.  Check -

Question: How can I expand the schema on a 32 bit windows 2003 server when Exchange is only 64 bit?

Answer: You can install Exchange 2007 on a 64 bit Windows 2003 server or use the 32 bit version to perform the Schema extensions.

Question: Does Microsoft still recommend using ISA to proxy requests to the CAS server? If not, then what security configuration is recommended for CAS operations?

Answer: Yes, we still recommend ISA for publishing Exchange resources to the Internet (the main server role is CAS). In lieu of using ISA, a third party product could be used.

Question: does Edge transport server require an exchange install since it is a pure SMTP server?

Answer: Yes, since the Edge Transport Server is one of the Exchange 2007 roles.  If you don’t install Exchange, you cannot have this role.

Question: Does Microsoft recommend using ISA to protect the Edge server from the Internet?

Answer: Although you can do this, it is not necessary as the Edge Server Role was meant to reside in the DMZ.

Question: to have an edge server and a server running the other roles you would need multiple exchange licenses?

Answer: Yes.  For each physical server that you install an Exchange Server 2007 Role onto, you will need an Exchange Server license.  To be safe, you should always check with your Microsoft Sales Representative or the licensing specialist from your reseller as licensing changes do occur from time to time.

Question: what are the minimum OS requirements for Exchange 2007

Answer: See the following ---

Question: I read the requirements for running a multi-role server and it said that the recommended minium RAM was 4GB if I remember correctly. How critical is it to actually have this much RAM for small business with possibly only 20 employees?

Answer: The bare minimum I would go with is 1 GB of RAM.  Personally, I would go with at least 2 GB of RAM [Harold]

Question: Is there any supported way to sync AD mail recipient information to the Exchange 2007 Edge Transport server in the DMZ from pure Exchange 2003 organization without introducing Exchange 2007 Hub server into the E2K3 org first?

Answer: No.  The Edge Sync feature is specific to the Hub Transport Role.

Question: It's possible recommended to install a GC at a virtual server or which role can be put at a virtual server and which NOT?

Answer: You should watch the individual product sites as well as the Virtual Server site for supported configurations.  Currently, we do not support any Exchange Server 2007 roles in a Virtual Machine.

Question: Does the Edge server have to be installed after the CAS and Transport Server roles?

Answer:  No.  Check out -

Question: Statistic gathering on Exchange 2003 was cumbersome without MOM. Does Exchange 2007 have good stats gathering tools built in?

Answer: Exchange does have *some* new logging features, but MOM is still the best option for monitoring Exchange

Question: 32 bits version only can use E2K7 for test environment, not for production

Answer: Yes

Question: Are there operations in the Command Shell that are NOT available in the GUI?

Answer: Yes. There are operations available only in the Command Shell that either did not make sense to have in the GUI or simply don't have a GUI equivalent.

Question: Is OMA still included in Exchange 2007?

Answer: No, OMA is no longer supported in Exchange Server 2007.

Question: Can there be multiple Hub Transport roles in a single domain forest?

Answer: Hub Transport You can deploy multiple Hub Transport servers for internal transport high availability. Resiliency has been designed into the Hub Transport, as well as the Mail Submission Service on Mailbox servers, for deployment of multiple Hub Transport servers.

Question: What's your recommendation to have High Availability for the CAS server, is clustering supported?

Answer: High Availability -

Question: so the hub server can interact with an appliance that sends and receives internet e-mail and the edge server role would not be needed?

Answer: The Edge Server Role is an optional role. There are 3rd party messaging / hygiene products you could use.  However, the Edge Sync capability only exists with the Edge Server Role.

Question: what would happen if Hub Transport Server goes down? Would there be breakdown in message transfer?

Answer: If the Hub Transport goes down (and another one doesn’t exist in the same AD site), email flow will stop.  The email will be queued until the Hub Transport comes on line.

Question: Is it possible to move roles off of a server as we grow if we start with a simple installation where all roles are installed on the same server?

Answer: Yes.

Question: do these Exchange security groups have explicit deny to send as and receive as at the Org level like in e2k3?

Answer: Yes.

Question: can there be multiple hub servers within a site to provide resiliency?

Answer: Yes

Question: Does the Hub Transport Server get involved even if the message goes within the same store?

Answer: Yes it does, all e-mail flows through Hub Transport including internal

Question: what is the thumb rule around how many HUB servers per site?

Answer: At least one Hub Transport per AD site in which a Mailbox Server is installed.  For redundancy, at least 2.

Question: Will permissions from E2K3 transfer to E2K7?

Answer: Yes, if you are referring to an Exchange Organization upgrade (installing Exchange e2007 into your existing 2003 organization)

Question: minimum OS requirements for installing Exchange 2007 pls..any links ?

Answer: See the following ---

Question: can you designate a primary hub server or does exchange handle that?

Answer: Exchange Server 2007 will automatically handle this.

Question: A client's Small Biz 2003 server was originally set-up to take over a Novell server role, The work station computers were created as part of the network and drives mapped as F:, G: etc without creating the computers under Active Directory my question is if there is a method to change the association of each work station, or whether I have to remove the original computer, then re-create it under the Active Directory?

Answer: This is not an Exchange question - However - if you wish for the machines to be properly joined to the Domain, then you will have to go through the domain join process. if there are conflicting computer accounts in AD, those should be reset or removed prior to joining the machines to the domain. This does not apply to Windows 9x machines.

Question: I have 5 sites in AD with 5 subnet properly configured. With one Ex2007 with 4 roles, do I have to modify anything? (I think, "NO")

Answer: You are correct. If you only have one Exchange 2007 Server with all 4 roles installed on it, there are no additional things from a routing perspective because everything will be on that one server.

Question: If you have two hub servers in one site, can you place preference on which hub server is used first?

Answer: Yes you can. By default, connections will be load balanced.

Question: Who can delegate a user to the EX Org Admin Role?

Answer: Someone who is already an Exchange Organization Admin.

Question: Do you have to run AD prep in domains where there are no Exchange 2007 servers? and in the empty root domain?

Answer: If you have objects that you will mail enable and also plan to use the Recipient Admin role, then yes. Otherwise, no.

Question: 4 or 5 Admin roles?

Answer: 4 admin roles - Exchange Org, Exchange Server, Exchange Recipient and Exchange View Only.

Question: when is pt2 is there a way to reg whole series at one time?

Answer: Part two is next Wednesday. I have Question to see if we can come up with a method to allow attendees to register once for the entire series. Stay tuned and look at my blog as I will post as soon as I hear.

Question: And who nominates the first ex org admin?

Answer: The person who installs Exchange (for new installs). For installs where you integrate with Exchange 2000 / 2003, existing Exchange Full Administrators.
