When I migrated mailboxes from exchange 2003 to exchange 2007 in my environment most of the mailboxes were migrated
successfully except for some users , for those user I found duplicate mailboxes one in exchange 2003 and the other one in
The one in 2007 is working fine but with some data loss
The one in 2003 shows a red cross and I can see that there is some data still in there, I only have purge and reconnect
option s, I tried to create new account and reconnect the mailboxes to that account but it fails
When I try to move the mailbox back from 2007 to 2003 it gives the following error
Summary: 1 item(s). 0 succeeded, 1 failed.
Elapsed time: 00:00:11
Error was found for mailboxname (firstname.lastname@example.org) because: Error occurred in the step: Preparing mailbox to be moved. Failed
to copy basic mailbox information with error: A duplicate mailbox was found due to problems during a Move Mailbox procedure.
The duplicate mailbox has been deleted. Try again later., error code: -1056749241
Exchange Management Shell command attempted:
‘xx.xx.xx/xx db/mailbox’ | move-mailbox -TargetDatabase 'EXCHANGE2003storagedb’
Elapsed Time: 00:00:11
Any idea how to solve this or at least to export those mailboxes to pst , I tried xmerge but it does not see those mailboxes
