Lync 2010 Group Chat and Privacy Mode
Topic Last Modified: 2011-02-01
When Microsoft Lync 2010 Group Chat is not the primary instant messaging (IM) and presence client and is running side-by-side with Microsoft Lync 2010, Lync 2010 Group Chat will not violate the Lync 2010 presence privacy mode.
Presence privacy mode works with Group Chat as follows:
Lync 2010 stops Group Chat from doing any access control entry (ACE) bootstrapping when running side-by-side with Lync 2010.
Group Chat can still display presence and can read and edit the Buddy List. If Group Chat stops IM, presence, and Buddy List operations when running with Lync 2010, Group Chat stops bootstrapping as well.
If Group Chat is running with IM and presence mode enabled, it bootstraps the default ACEs, thus effectively overriding presence privacy mode. Presence privacy mode will not work in this scenario.
If Microsoft Lync Server 2010 is running in presence privacy mode, Group Chat must be configured with its IM and presence mode disabled, or Group Chat reverts out of presence privacy mode.
You must run Group Chat on the same computer as Lync 2010 for them to work side-by-side in presence privacy mode.
You can run Group Chat without Lync 2010 and still run Lync 2010 in presence privacy mode on another computer, as long as you keep IM disabled on the computer running Group Chat. We do not recommend this scenario.
