I need to know what is the best and easy way to merge or restore old emails into users mailboxes.
We have two office locations(local and remote), our remote office exchange server was crashed and we decided to create dial tone database on local office exchange server and then moved remote users with -configuration only option and given then blank mailboxes so they can start sending/receiving emails, which is working fine.
Now we have received backup tape drive from remote office wanted to restore/merge old emails into their new mailboxes.
I need to know what are the options to accomplish this.
Please note, we can't use these backup tapes into our existing backup software because remote office were using different software so we managed to build offline backup server and trying to retrieve exchange data / flat files or mailboxes from the tape.
