* Previous releases are partially supported. In these scenarios, the LRS client can participate in Lync conferences (those that are scheduled by users homed on Lync Server 2010) as long as the conferences are “public,” meaning the conferences aren’t customized for restricted access.
The LRS client cannot be homed on a Lync server version earlier than Lync Server 2013. When an LRS cannot connect to Exchange to retrieve calendar settings, for example when there is no Exchange mailbox configured for the LRS account or Exchange is not reachable, Meet Now and ad hoc conferencing will work, but joining a scheduled meeting will not work.
