I have tried to move my exchange users to a fresh exchange 2000 organisation from exchange 5.5. Having upgraded to Active directory from NT using active directory connector, the users that had mailboxes in the exchage 5.5 server still have that server as the "home server" in his properties. The option to create mailboxes for these users is not provided in the exchange tasks. For new users all exchage features are provided. I have tried the migration wizard (e2k sp2) and that doesn't help. "canot create mailbox" with error message eventid 15020, source: msexchageMig. can anyone please help.
