User in a DG cannot join a chat room in a Lync Server 2013 environment

Symptoms
Consider the following scenario:
  • You deploy a Persistent Chat server in a Microsoft Lync Server 2013 environment.
  • You add a distribution group (DG) as a chat room member in the Lync Server 2013 environment.
  • A user in the DG signs in to Lync 2013.
In this scenario, the user does not receive chat room invitations. Additionally, users in the DG cannot join the Group Chat room.
