Question

You are deploying Microsoft Teams with media optimization on a pooled AVD host pool running Windows 11 Enterprise multi-session. You have already installed the WebRTC Redirector Service and set the registry key IsWVDEnvironment to 1. When you install the Teams desktop client, users report that Teams runs in a non-optimized state and calls place high CPU load on the session hosts. What is the MOST likely cause?

Accepted Answer

Teams was installed per-user rather than in per-machine (ALLUSERS) mode on the multi-session image.

Answer

The FSLogix Office Container was not configured to include the Teams cache folder.

Answer

RDP Shortpath was not enabled, forcing media over the TCP relay path.

Answer

The session hosts are missing the GPU driver extension required for Teams video encoding.
