Exchange 2003 - 2010 migration Outlook connection query

Hi, I am planning the upgrade from Exchange 2003 - Exchange 2010.  My query relates to the client connection via Outlook 2010 (and 2007).

We have 'hard coded' the Outlook profile with Office customisation / custom install so each Outlook client has %username% and internal.servername.com so Outlook knows where to find the exchange server. (Clients are Windows 7 32-bit with Office/Outlook 2010 or 2007).

My question is, once I start migrating user mailboxes, if the user mailbox has moved to Exchange 2010 will Autodiscover over write the above 'hard coded' outlook profile?

Hardcoding the Exchange server was a mistake, a pretty common mistake I have to say, but will become a problem.
Outlook will be updated automatically by Exchange to point to the new server. However that will need to happen each time because your setting will almost certainly overwrite it when Outlook next starts. Outlook will then connect to the old server, and be redirected. All the time that the old server is still available, that will be fine.
It isn't Autodiscover doing that - but an Exchange process - basically Exchange saying that the email isn't here (Server 1) but there (Server 2).

There are two suggestions I would make here:

1. Deploy an RPC CAS Array. This is effectively a virtual Exchange server that exists in DNS. That will allow you to change the configuration of your Outlook deployment to allow Autodiscover to work - you can remove any kind of hard coding.

2. When you have removed the Exchange 2003 server, adjust the DNS to point to the Exchange 2010 server, and also add in a NETBIOS alias for the old server. That can only be done when the old server has been completely removed, including being dropped from the domain.

I would then work to remove the hard coding from your Office installations.

Hi Simon

To clarify, when Outlook is opened, it points to Ex2003 (from Office custom install, hard coding), but will then be updated re-pointed to Ex2010 by the Exchange process.  And it will have to do this each time until the hard coding is removed from the office deployment, and   this would make Outlook slow to respond / load / connect when launched?

Following on from your suggestions, can you provide any site links for reference?

The DNS step 2, you mean create a  cname OR Host A record like 'Ex2003.internal.domain.com to Ex2010.internal.domain.com'

thanks Richard

Otherwise you are correct.
