We have an Exchange 2007 environment, we moved mailboxes from one mailbox store to another. We were able to send/recieve without any issues from a Blackberry device. After opening the mailbox all of the "old" information that was in database A has not moved over to Database B. We can see the files in the database A, but cannot get them to Database B. It is almost as if it created a new mailbox instead of moving the mailbox from Database A.
