Migration from 5.5 issues

[Callahan]

Hi,

I've just started with a company that are in the middle of migrating their Exchange 5.5 server to Exchange 2003. The guy I've replaced had set up the AD connector incorrectly and it has caused all sorts of weird things to happen. During our talks about how to fix the problems I had a thought regarding the way Outlook talks to Exchange. When you set up a new account in Outlook and point it at the Exchange server, how does it resolve the name? We are in a native environment - all 2K/2003/XP and they have the new Exchange server set up with the same name as the old Exchange server. Wouldn't this cause odd behaviour? Our main problem is that some users have been doubled up after an attempt to move their accounts to the new Exchange Server whereby they have Contacts and mailboxes. Deleting a contact seems to also delete the mailbox.
I'm guessing that because they have 2 Exchange servers named the same, this is what is causing them to see 2 instances of some mailboxes, each of them a full mailbox.

Any ideas?...

Scratch that. Seems that the 2 servers with the same name were not both exchange servers. Despite this, the initial question remains. We are left with contact duplications of existing mailboxes so it anyone has experienced this I'd be grateful for any pointers...

You have asked a big and broad question. Can you start at one problem and we can help you each way.

What is installed so far? Are 5.5 and 2003 co-existing?
