With Exchange 2003, if you wanted to create Active Directory accounts based on the list of disconnected mailboxes in the mailbox database, you could use the Mailbox Export Wizard which was a part of the Mailbox Recovery Center. Before that, you could have used MBCONN, a tool we had for that purpose. That functionality would let you create a LDF file for AD import, based on the list of disconnected mailboxes in the mailbox database, in case you needed to bulk create AD accounts that you can then connect those mailboxes to.

But - how do you do this in Exchange 2007?

With the latest Exchange 2007 documentation update, we have now documented this procedure:

How to Generate Active Directory Accounts By Using the Mailbox Information in the Mailbox Database

Thanks to Marc Nivens for writing the script and all other members of the Exchange Team that were involved in publishing this!
