We recently had some corruption in our Exchange 2007 database which required us to create a new database and move all mailboxes to a new/clean database. During the migration to a new database we discovered the user that had the corrupted mailbox "John Doe". Everyone else's mailbox migrated beautifully but we had issues as his mailbox was corrupted. Our first attempt was to migrate his data to a pst and we performed and import of the PST to his new mailbox which did not work well. Because of the import attempt, he had a new mailbox associated with his account. We decided to disable this new mailbox (which put his mailbox into a "Disconnected" state. We then created a new mailbox for "John Doe" and manually copied his PST information into the corresponding locations within the new mailbox. Long story short is:
1. We have a single new clean database with all users including "John Doe"
2. After creating the new mailbox for John Doe and importing his information, I still see the old mailbox in the Disconnected state which makes sense.
3. The question is, what happens when exchange finally deletes the disconnected mailbox? I assume that Exchange distinguishes the difference between a live/connected mailbox for "John Doe" and the disconnected mailbox for "John Doe" and that the disconnected mailbox will be the only one purged (as I no longer need it anyway)? I was going to manually delete the mailbox using the Exchange command but wanted to make sure that it only deletes the old/disconnected mailbox for "John Doe" and does not impact his live/working mailbox. I assume Exchange has some type of SID that is tied to the mailboxes to distinguish between them? Any insight would be greatly appreciated!
