We used to run purely Exchange 5.5. We had two 5.5 servers and mailboxes were split between them. Then we put in an Exchange 2003 machine, using Active Directory Connector to connect to the older 5.5 server running on NT4 (SP6a). I started moving mailboxes over there ... eventually all of the mailboxes were off one of the 5.5 servers (we still have some mailboxes on the other 5.5 server). I want to remove this server from our network, but it seems that everytime I turn it off people start complaining about Outlook features (speciafically Calendar items) not working correctly. I crank up the old 5.5 server and the problems go away. Any ideas?
This is a long shot (I'm not an Exchange guru), but would it have anything to do with the System Attendant on the old 5.5 server? Or, maybe the fact the 5.5 server I'm trying to take offline was the original 5.5 server. At any rate, I want to get this thing off my network. Plus, I'm soon to have all the mailboxes on the new 2003 server and I'll want to remove the other 5.5 server at that time. What could be the hangup?
I'm open to suggestions ... fire away. If you need more detail please let me know. Thanks.
