Administering Address Book Servers

Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

The Address Book Server runs as a part of the Office Communications Server Front End service. This service runs on the following servers:

  • Standard Edition Server

  • Front End Server in an Enterprise pool

The Address Book Server performs two important functions:

  • The primary function is providing global address list information from Active Directory to Office Communications Server 2007. If Communicator accesses Active Directory directly, it could affect network performance. To make address book updates faster and more efficient, the Address Book Server acts as an intermediary to provide the updated local copy of the address list to the Communicator client.

  • The secondary and optional function is performing phone number normalization for Communicator telephony integration. For more information about phone number normalization, see the Microsoft Office Communications Server 2007 Enterprise Voice Planning and Deployment Guide.

Administering Address Book Servers includes the following:


The ABS Configuration Tool (ABSConfig.exe), which is available in the Office Communications Server 2007 Resource Kit Tools, provides a graphical interface to configure the Address Book Server settings. You can download the Resource Kit Tools from the Microsoft Web site at
