Change the Default Offline Address Book

 

Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2

By default, when you install the Mailbox server role, a Web-based default offline address book (OAB) named Default Offline Address Book is created. You can set any OAB in your Exchange organization as the default OAB. This new default OAB is associated with all newly created mailbox databases. You can have only one default OAB in your organization. If you delete the default OAB, Microsoft Exchange doesn't automatically assign another OAB as the default. You must manually designate another OAB as the default.
