Exchange restoration

Okay, this scenario is based around someone’s exchange mail having gone missing (largely); so their mailbox is still there, but they’ve lost a lot of mail due to faulty archiving.

  • Back up current mailbox contents to a PST
  • Delete user and mailbox*
  • Restore exchange mailbox store from backup (to recovery storage group)
  • Dismount "live" store; copy .stm and .edb from recovery group to "live" location
  • Enable database over-write
  • mount copied store
  • create matching AD user without any mail features
  • Reconnect user mailbox to new AD user

*This might work just by removing users exchange featurs rather than deleting AD account but untested.

This will be edited, I just had to note down the steps while it was still fresh in my mind.
