Lync Room System Interoperability with a Lync Server 2010 Pool

During migration, if a user who is homed on a Lync Server 2010 pool schedules a meeting and invites the LRS account, the LRS client will have limited functionality while attending the meeting.

When the LRS client joins a scheduled conference call that has been organized by a user homed on Lync Server 2010, LRS has the following in-meeting limitations:

• LRS cannot show the multi-view video gallery.
• If the LRS client is the presenter, it cannot apply video lock on participants.
• LRS cannot show 1080p video resolution (inbound or outbound), even if the Lync Server 2013 conferencing policy allows it, because of the following:
  • Lync Server 2010 doesn’t support 1080p resolution.
  • LRS is always limited by the organizer’s conferencing policy for video resolution. Therefore, even if the Lync 2010 pool supports 720p resolution, LRS will not be able to take advantage of 720p resolution as long as organizer’s policy doesn’t support it.
• Lync 2013 clients detect LRS presence in the meeting room, and they auto-mute themselves to avoid echo in the physical meeting room. This feature does not work in meetings hosted on Lync Server 2010.
• There are limitations on desktop sharing performance for meetings hosted on Lync Server 2010.
• Users won’t be able to join private (restricted) meetings that are hosted on Lync 2010 with LRS.
