Recovering an Exchange Offline Address Book Server
Recovering an Exchange Offline Address Book Server
The process required to restore an Exchange Offline Address Book (OAB) server is similar to the procedure you would follow to recover a public folder or mailbox server: without touching any objects in Active Directory, perform a recovery according to the instructions provided in Exchange Server 2007 Disaster Recovery.
Essentially, you will rebuild server using the same name, reinstall Exchange using 'setup /m:RecoverServer', and then restore the public folder database from the most recent backup.
