  • Recover mailboxes in a new AD environment

    Hello everyone!

    I hope you can help me with this, as i have run out of ideas.

    I recently had a disaster recovery situation in a client without a system state backup. I only had an exchange backup.

    The server was in an unbootable state with corrupted filesystem, so I had to reinstall SBS 2003. I reinstalled with the same server and domain names. added users with the same exact names and managed to setup a Recovery Storage group from the exchange backup. I can see all the old mailboxes but can't manage to merge them with the new ones. when i try to do so, i get an error stating that the login attempt to the exchange server failed and error events 9175, 9167 and 1041 in event viewer.

    I also tried to export mailboxes to PST with exmerge, but this fails with errors like "Error! Cannot identify the user with the msExchMailboxGuid p\B8\A9\AAfdFK\8B\1F\DE\84\C4\C1\ED\8A."

    It's very frustating to see all my mailboxes and still can't be able to tap them. please help!

    Thank you!

    That's because the original mailbox no longer exists and ExMerge is trying to map it to GUID of the original mailbox.

    You would need to amend the mailbox GUID in ADSI to whatever it was stamped with previously.

      Not cheap, but Ontrack PowerContols is ideal for this sort of situation:

        Kernel is my choice for this as a last resort.

        They provide a demo that is limited. A full version will set you back at least 250 or so. It's a very simple utility to use and can recover mailbox data from corrupt databases. Although in the OP's case his is a GUID mismatch which may be resolvable.

          That seems to work.

          I delete de mailboxes, run cleanup agent, stop information store, replace database with the one i had in RSG, attach the mailboxes again and am now able to export the mailboxes to PST.
          the only problem is that when i revert to the original database, i can no longer login to the user mailbox, so i'll try this in a lab server i'm seting up.

          Thanks for the reply
