Change the default offline address book
Applies to: Exchange Online, Exchange Server 2013
Topic Last Modified: 2014-12-16
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.
For additional management tasks related to OABs, see Offline address book procedures.
Estimated time to complete each procedure: 5 minutes.
You need to be assigned permissions before you can perform this procedure or procedures. To see what permissions you need, see the "Offline address books" entry in the Recipients Permissions topic.
By default in Exchange Online, the Address List role isn’t assigned to any role groups. To use any cmdlets that require the Address List role, you need to add the role to a role group. For details, see the “Add a role to a role assignment policy” section of Manage role assignment policies.
You can’t use the Exchange Administration Center (EAC) to perform this procedure. You must use the Shell.
