Question : Microsoft Exchange Mailboxes

I recently lost two domain controllers which had an exchange server attached to it. Someone needs there mail off of the exchange server.

Is it possible to extract the mail from the exchange server without the domain controllers?

Answer : Microsoft Exchange Mailboxes

Yes you can, you just need to have an exchange server with exactly the same name and exchange structure. It's quite simple. just install a server with the same name as the one that failed, the install exchange with the same exchange name for administrative groups, and finally move the old database to you new server.
