There is a bug in Exchange 2007 when you decide to designate a new server responsible for generating the offline address book (OAB).

Move-OfflineAddressBook will give an error and fail if the target server doesn't already have the ExchangeOAB folder. This only occurs on Exchange 2007 to Exchange 2007 moves. To get around this, the Administrator needs to create a dummy OAB and build it, then move the desired OAB, delete the dummy OAB, and delete the dummy OAB files from the ExchangeOAB directory.
