I am trying to retire the old Exchange 2003 server now that we have migrated over to 2007. When I try to remove Exchange 2003, it reports that one or more users currently use a mailbox store on this server.
There are 4 mailboxes listed on that server
William Hare (an old user account that does not exist anymore)
It will not allow me to move or delete the last two mailboxes listed. I have tried Cleanup Agent, Offline Defrag and Repair, but they still remain.
How can I complete the removal of Exchange from this server?
