This step-by-step article describes how to enable the Hierarchical Address Book (HAB) feature in Microsoft Exchange Server 2010. The HAB is a feature in Exchange Server 2010 and the Office Outlook 2010 address book. The HAB lets end-users browse for recipients in their Exchange organization by using an organizational hierarchy.

You must have the Active Directory Service Interfaces (ADSI) Edit snap-in to complete some of these steps.

Warning If you use the ADSI Edit snap-in, the Lightweight Directory Access Protocol (LDAP) utility, or any other LDAP version 3 client, and you incorrectly change the attributes of Active Directory objects, you can cause serious problems. These problems may require you to reinstall Microsoft Windows Server, Microsoft Exchange Server, or both Windows and Exchange. Microsoft cannot guarantee that problems that occur if you incorrectly modify Active Directory object attributes can be resolved. Change these attributes at your own risk.

More information

The Hierarchical Address Book (HAB) is an Outlook address book that lets end-users browse recipients in the organizational hierarchy that they belong to. The HAB is enabled by creating a root organization that will be the top of the hierarchy. After you create a root organization on Exchange Server, Outlook 2010 automatically detects when the feature is enabled and adds the Organization tab in the Outlook Address Book dialog box. End-users can use the Hierarchical Address Book and the name list, such as the global address list, by switching tabs. The screen shot for this step is listed below.
