Hi Chris, How about DoeJ's mailbox? Does it works? Please run the cmdlet Clean-MailboxDatabase. Please check whether the mailbox will be listed in the Disconnected Mailbox. Did you select the "Do not permanently delete itmes until the database has been backed up" in the resource database's properties? If yes, please temp disable it. Frank Wang

Hi Chris, How about your question? Any updates?Frank Wang

I've suffered the same thing when moving mailboxes from one database to another on the same server. It moves ok, but the deletion of the old mailbox fails. The new mailbox works fine. Running a clean puts the mailbox into the disconnected items. Running a remove says it is still connected to the moved mailbox user. Moving the user back to the orginal store says there is a duplicate and removes the duplicate. (The move doesn't complete) The disconnected mailbox is then removed. Email to the moved user, during all this and afterwards continues without issues (so far I HOPE!!) I had this issue when I had a corrupt database and decided to create a new database and move all the mailboxes over, it happened for about 80% of the users. I've now dismounted the store and everything still seems ok. Not sure if this is releated to this thread, but thought I'd add my 2 penneth worth of information Dave
