- You sign in to a Microsoft Lync 2010 client by using the Lync Online service.

This issue occurs because the last web ticket is fetched from the director instead of the front-end server.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
