I have an Exchange 2007 Mailbox server, which had accumulated significant white space. I performed a mailbox move to another storage group, recreated a new blank DB. I then moved all the mailboxes to the new DB. I then moved this DB back into the original Storage Group.
While this process was successful, I noticed that all the mailboxes had shown up in the "Disconnected Mailboxes"
Could someone please explain why this happened and how can I solve this before anything drastic occurs.
