Consider the following scenarios when you use the Address Book Service Configuration tool (ABSConfig.exe) to customize the Address Book Service configuration in Microsoft Lync Server 2010.
You cannot restore the default attributes correctly when you click the Restore defaults button in the ABSConfig tool.
You delete certain RTM attributes. For example, you delete the Title attribute.
You re-create certain customized attributes by using the ABSConfig tool. For example, you create the Customerizedtitle attributes.
You run the setup files of the ABSConfig tool.
In this scenario, the customized attributes are removed unexpectedly.
This issue occurs because the attributes of Lync Server 2010 are not restored. Instead, the default attributes of Microsoft Office Communications Server 2007 R2 are restored.
This issue occurs because the ID for the customized attribute is generated by the same ID for one of the RTM attributes.
To resolve this issue, install the following updates:
