Recover Exchange 2003 Mailboxes to Different Exchange 2003 Server


I will try and keep it simple.  We had two Exchange 2003 Standard Edition servers running on Windows Server 2003 (Server A and Server B).  Server A crashed and we were not able to recover the full server with our backup software yet.  However, my question is if it is possible to use the database backup that belonged to server A and recover the mailboxes to server B.  Server B is a member of the same Exchange organization as A.  If more information or clarification is needed, please let me know.

Please follow this article, it will give you more details It is possible you can restore Exchange 2003 DB on another mailbox server if it is in same Administrative Group.

This article describes the new Recovery Store Group feature in Exchange Server 2003. By using the Recovery Storage Group feature, you can mount a second copy of an Exchange mailbox store (database) on the same computer as the original mailbox store, or on any other Exchange computer that is in the same administrative group. You can use the Recovery Storage Group feature to recover mailbox data without having to install and to configure a separate Exchange recovery computer.

This article contains information about how the Recovery Storage Group feature works. This article discusses how to create a Recovery Storage Group, how to restore mailbox data to a Recovery Storage Group, and how to extract recovered mailbox data from the Recovery Storage Group.

If the server has failed, then recover it.
If you have the databases that is all you need.

RESET (NOT DELETE) the computer account.
Rebuild Windows 2003 to the same patch level as it was before.
Install Exchange 2003 from the command line with the /serverrecovery switch.

Then install SP2. You should then be able to mount the original databases back in the server.

By doing it that way, there is no heavy clean-up of the domain to do to remove the failed server.

Thank you for the article link, it was a good read!  Ultimately, the solution route we took was to mount the failed server's database onto the surviving server and re-home the user mailboxes.  There was actually more work along the way to get us to that point, but it was not difficult.  To Simon's point, we did have to do some AD cleanup for the failed server
