Cancelled mailbox moves in Exchange 2007

You cancel a mailbox move.  How do you clean out the target database of the email that was copied?  Or, a related question, if you move the same mailbox again to the target database, will the email that has already been copied to the target database be copied again?

When u cancel a mailbox, a duplicate mailbox is created on the target store.
Run clean-mailboxdatabase to know the actual status of the mailbox, u will see a disconnected mailbox in the target store.
If u see the mails in the source mailbox is missing, u can connect the disconnect mailbox with a test account, export data to PST.
If u have all the mails in the source mailbox, Again move the mailbox from the source to target store, on completion u will see a the same mailbox in the target store with the same data.

Thanks.  I will try the suggestion tonight.  Just another issue.  I note that the mailboxes that made the move successfully are also successfully receiving and sending email.  However, the timestamp on the database has not changed since the time when the database was created and the moves, including the cancelled moves, were run (yesterday morning).  I'm wondering if this spells trouble of some sort.

Typically, if you cancel a mailbox move, the data remains complete in the source mailbox. If you attempt to move the mailbox again, it will say the destination mailbox already exists, but it will then remove it. The next attempt will work. As for the timestamp issue, I don't think this is a problem. It may just be reporting the creation date/time. As long as the messages are flowing to/from the mailbox, then you have a successful migration.
