All Exchange administrators will eventually come to a point where they have to forcefully update the Exchange offline address book (OAB). However this is not as straight forward as one would hope. The following steps have to be taken to force an update.
- In the Exchange Management Console go to Organization Configuration and select Mailbox.
- Go to the Offline Address Book tab
- Right-click the address book that you want to update and select Update
That much was quite straight forward. Now to have the OAB be available right away you’ll have to restart the Microsoft Exchange File Distribution service.
All of this can also be done in powershell by running the following commands.
Get-OfflineAddressBook | Update-OfflineAddressBook
net stop MSExchangeFDS && net start MSExchangeFDS
