I've just finished migrating the company from Exchange 2000 to Exchange 2003 and was on the final steps of attempting to uninstall the Exchange 2000 server and experiencing a problem.
Up to this point I have:
-upgraded AD from 2000 to 2003
-added the new W2K3 server as domain controller / installed Exchange 2003
-completed all the prep work and moved users mailboxes
-Moved / Rehomed public folders
-Shut down services on old server and have run successfully for about a week now..
Used following whitepaper as a guide:
Now on the final step, attempting to uninstall Exchange 2000 and getting the following error:
"The component Microsoft Exchange Messaging and Collaboration services cannot be assigned the action of Remove because:
One or more users currently use a mailbox store on this server. These users must be moved.............. "
The only 3 mailboxes I see left on the old exchange server are:
- SMTP - %servername%
- System Attendant
and their counterpart mailboxes ARE created and running on the new server, so not sure what to do or where to look at this point...
