Symptoms

Consider the following scenario:

  • User A uses a Microsoft Office Communicator 2007 R2 client to log on to a Lync Server 2010 environment.

  • The Public Instant Messaging (IM) Connectivity (PIC) feature is enabled in the Lync Server 2010 environment.

  • User B is using a public IM client, such as Windows Live Messenger, AOL, or Yahoo. User B types in the Session Initiation Protocol (SIP) Uniform Resource Identifier (URI) of user A.

In this scenario, user B can view the status of user A, and send instant messages to user A.

Cause

This issue occurs because the Office Communicator 2007 R2 client misinterprets a new container manifest setting. Therefore, the Lync Server 2010 server incorrectly treats user B as a colleague or as a workgroup.
