    Hi,

    we are facing application sharing issue in SFB conference.

    Hi Deepak,

    Check the network quality is good.

    Check Conference server is not overloaded .

    You can switch VbSS based sharing to RDP based sharing. It will significantly reduce the AVG tile processing latency, and in my experience the RDP based performance has been better too as compared to VbSS.

    For testing, you can create a new conferencing policy with AppSharingMode to RDP and test it with a small group of users.

    You can use global Set-CsMediaConfiguration cmdlet to turn-off Video based Screen Sharing.
