OAB (offline address book)

An Offline Address Book (OAB) is a downloaded copy of a Microsoft Outlook user's address list which allows the user access to email addresses when disconnected from Exchange Server.

Exchange administrators can configure which Offline Address Books users can access, as well as how the OABs are distributed.
