Consider the following scenario:
You have a computer that is running Windows RT 8.1, Windows 8.1, or Windows Server 2012 R2.
You use Microsoft Lync 2013 to share your desktop or applications with another Lync 2013 user.
Another Lync user uses Lync 2013 on a Remote Desktop Protocol (RDP) client that has the thin client mode enabled.
In this scenario, the Lync 2013 sharing performance is slow: content update on the sharing window takes 10 to 15 seconds.
Note This issue occurs on the following versions of Lync:
Lync 2013 for desktop
Lync application for Windows
This issue occurs because of a mismatched behavior between the RDP client and the Lync 2013 client.
