Redirect Outlook 2003 clients from removed Exchange 2003 server to new Exchange 2007 server

[spyordie007]

I have something I'm working on that I?m hoping I can get some new ideas for.

I have a mixed environment I?m working with that has one Exchange 2003 and 4 2007 servers (2x MBX, 2x CAS/HT). Clients are approximately 90% 2003 and 10% 2007.

The 2003 server needs to be decommissioned and removed however there are a number of clients that have not connected and re-homed to the 2007 servers where their mailboxes reside. I?m trying to come up with a way to allow the clients to connect up to the 2007 mailbox servers when the 2003 one disappears and have not had much luck finding documentation.

I can?t redirect the clients to a 2007 mailbox server using a DNS record because Kerberos authentication fails. Exprofre doesn?t work either since the ExchangeLegacyDN doesn?t get changed.

Anyone have suggestions that will allow me to remove the 2003 server? I'm looking for something that will be transparent to the end users and no idea is a bad one (I've been going non-stop all week so I may very well have overlooked something simple).

Leave both servers online and functional. Use the Move Mailbox wizard to move the users from the 2003 server to the 2007 server. Clients should lookup their server from AD and seamlessly connect, is that not working?

That's working fine, I need to take the 2003 server offline next week.

If the clients are not logged on to the network, they will look up their server from AD. As long as the mailbox is moved they should connect to the new one.

2007 clients have no problem getting redirected for that reason, the issue is with the 2003 clients who do not get redirected until they first connect to the old server.

Convert it to a virtual machine and run it off a desktop machine for redirects?

That's creative I like it... but I'm supposed to be getting rid of this last Exchange 2003 server and that kind of defeats the purpose 🙂

I wonder if there would be a way to run some other (non-exchange) mapi redirect from another server...
