Consider the following scenario:
- You install the cumulative update for Microsoft Lync Server 2010 that was released in July, 2011 in a Lync Server 2010 environment.
- You start the Address Book Service Configuration (ABSConfig.exe) tool and change certain settings.
- You restart the tool.
This issue occurs because the ABSConfig.exe tool cannot read the configuration data from the most recent time that you made changes.
