You can’t remove an ABP if it is assigned to a user’s mailbox. To determine if an ABP is assigned to a user, run the following command in the Shell:

Get-Mailbox | Where $._AddressBookPolicy -eq <AddressBookPolicyName>

To remove an ABP from a user’s mailbox, you can use the Mailbox Settings tab of the mailbox’s property page or the Set-Mailbox cmdlet. For details, see Configure User and Resource Mailbox Properties.

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Address book policies" entry in the Mailbox Permissions topic.

1. In the console tree, navigate to Organization Configuration > Mailbox.
   
   
2. In the result pane, on the Address Book Policies tab, select the ABP you want to remove.
   
   
3. In the action pane, click Remove.
   
   
4. In the warning dialog box that appears, click Yes to remove the ABP.
