This topic explains how to use the Exchange Management Console or the Exchange Management Shell to change the default offline address book (OAB).
By default, when you install the Mailbox server role, a Web-based default OAB named Default Offline Address Book is created. However, 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 Server 2007 does not automatically assign another OAB as the default. You must manually designate another OAB as the default.
To perform the following procedure, the account you use must be delegated the following:

Start the Exchange Management Console.
In the console tree, expand Organization Configuration, and then click Mailbox.
In the result pane, click the Offline Address Book tab, and then click the OAB that you want to set as the default OAB.
In the action pane, click Set as Default. A warning dialog box appears. Click Yes to confirm that you want to set this OAB as the default OAB.
