We had recently run a successful bricks-level backup on our Exchange mailboxes; we hadn't done it before and likely won't be doing it again since it took 3 days to do. We would like to duplicate the mailboxes from within the backup so we can have an onsite and offsite copy, but when I go to select the mailbox backup from within the backup set it's not there. I checked the report, and all of the mailboxes backed up successfully. Is it not possible to duplicate a bricks-level mailbox backup from an existing set?
