Use Microsoft Teams on Azure Virtual desktop
Media optimization for Teams is supported for Microsoft 365 Government (GCC) and GCC-High environments. Media optimization for Teams is not supported for Microsoft 365 DoD.
Media optimization for Microsoft Teams is only available for the Windows Desktop client on Windows 10 machines. Media optimizations require Windows Desktop client version 1.2.1026.0 or later.
Microsoft Teams on Azure Virtual Desktop supports chat and collaboration. With media optimizations, it also supports calling and meeting functionality. To learn more about how to use Microsoft Teams in Virtual Desktop Infrastructure (VDI) environments, see Teams for Virtualized Desktop Infrastructure.
With media optimization for Microsoft Teams, the Windows Desktop client handles audio and video locally for Teams calls and meetings. You can still use Microsoft Teams on Azure Virtual Desktop with other clients without optimized calling and meetings. Teams chat and collaboration features are supported on all platforms. To redirect local devices in your remote session, check out Customize Remote Desktop Protocol properties for a host pool.
Before you can use Microsoft Teams on Azure Virtual Desktop, you'll need to do these things:
- Prepare your network for Microsoft Teams.
- Install the Windows Desktop client on a Windows 10 or Windows 10 IoT Enterprise device that meets the Microsoft Teams hardware requirements for Teams on a Windows PC.
- Connect to a Windows 10 Multi-session or Windows 10 Enterprise virtual machine (VM).
Install the Teams desktop app
This section will show you how to install the Teams desktop app on your Windows 10 Multi-session or Windows 10 Enterprise VM image. To learn more, check out Install or update the Teams desktop app on VDI.
Prepare your image for Teams
To enable media optimization for Teams, set the following registry key on the host:
From the start menu, run RegEdit as an administrator. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Teams. Create the Teams key if it doesn't already exist.
Create the following value for the Teams key:
Install the Teams WebSocket Service
Install the latest version of the Remote Desktop WebRTC Redirector Service on your VM image. If you encounter an installation error, install the latest Microsoft Visual C++ Redistributable and try again.
Latest WebSocket Service versions
The following table lists the latest versions of the WebSocket Service:
Updates for version 1.1.2110.16001
- Fixed an issue that caused the screen to turn black while screen sharing. If you've been experiencing this issue, confirm that this update will resolve it by resizing the Teams window. If screen sharing starts working again after resizing, the update will resolve this issue.
- You can now control the meeting, ringtone, and notification volume from the host VM. You can only use this feature with version 1.2.2459 or later of the Windows Desktop client.
- The installer will now make sure that Teams is closed before installing updates.
- Fixed an issue that prevented users from returning to full screen mode after leaving the call window.
Updates for version 1.0.2106.14001
Increased the connection reliability between the WebRTC redirector service and the WebRTC client plugin.
Updates for version 1.0.2006.11001
- Fixed an issue where minimizing the Teams app during a call or meeting caused incoming video to drop.
- Added support for selecting one monitor to share in multi-monitor desktop sessions.
Install Microsoft Teams
You can deploy the Teams desktop app using a per-machine or per-user installation. To install Microsoft Teams in your Azure Virtual Desktop environment:
Download the Teams MSI package that matches your environment. We recommend using the 64-bit installer on a 64-bit operating system.
The latest update of the Teams Desktop client version 1.3.00.21759 fixed an issue where Teams showed UTC time zone in chat, channels, and calendar. The new version of the client will show the remote session time zone.
Run one of the following commands to install the MSI to the host VM:
msiexec /i <path_to_msi> /l*v <install_logfile_name>
This process is the default installation, which installs Teams to the %AppData% user folder. Teams won't work properly with per-user installation on a non-persistent setup.
msiexec /i <path_to_msi> /l*v <install_logfile_name> ALLUSER=1
This installs Teams to the Program Files (x86) folder on a 32-bit operating system and to the Program Files folder on a 64-bit operating system. At this point, the golden image setup is complete. Installing Teams per-machine is required for non-persistent setups.
There are two flags that may be set when installing teams, ALLUSER=1 and ALLUSERS=1. It is important to understand the difference between these parameters. The ALLUSER=1 parameter is used only in VDI environments to specify a per-machine installation. The ALLUSERS=1 parameter can be used in non-VDI and VDI environments. When you set this parameter, Teams Machine-Wide Installer appears in Program and Features in Control Panel as well as Apps & features in Windows Settings. All users with admin credentials on the machine can uninstall Teams.
Users and admins can't disable automatic launch for Teams during sign-in at this time.
To uninstall the MSI from the host VM, run this command:
msiexec /passive /x <msi_name> /l*v <uninstall_logfile_name>
This uninstalls Teams from the Program Files (x86) folder or Program Files folder, depending on the operating system environment.
When you install Teams with the MSI setting ALLUSER=1, automatic updates will be disabled. We recommend you make sure to update Teams at least once a month. To learn more about deploying the Teams desktop app, check out Deploy the Teams desktop app to the VM.
Verify media optimizations loaded
After installing the WebSocket Service and the Teams desktop app, follow these steps to verify that Teams media optimizations loaded:
Quit and restart the Teams application.
Select your user profile image, then select About.
If media optimizations loaded, the banner will show you Azure Virtual Desktop Media optimized. If the banner shows you Azure Virtual Desktop Media not connected, quit the Teams app and try again.
Select your user profile image, then select Settings.
If media optimizations loaded, the audio devices and cameras available locally will be enumerated in the device menu. If the menu shows Remote audio, quit the Teams app and try again. If the devices still don't appear in the menu, check the Privacy settings on your local PC. Ensure the under Settings > Privacy > App permissions - Microphone the setting "Allow apps to access your microphone" is toggled On. Disconnect from the remote session, then reconnect and check the audio and video devices again. To join calls and meetings with video, you must also grant permission for apps to access your camera.
If optimizations do not load, uninstall then reinstall Teams and check again.
Known issues and limitations
Using Teams in a virtualized environment is different from using Teams in a non-virtualized environment. For more information about the limitations of Teams in virtualized environments, check out Teams for Virtualized Desktop Infrastructure.
Client deployment, installation, and setup
- With per-machine installation, Teams on VDI isn't automatically updated the same way non-VDI Teams clients are. To update the client, you'll need to update the VM image by installing a new MSI.
- Media optimization for Teams is only supported for the Windows Desktop client on machines running Windows 10.
- Use of explicit HTTP proxies defined on the client endpoint device is not supported.
Calls and meetings
- The Teams desktop client in Azure Virtual Desktop environments doesn't support creating live events, but you can join live events. For now, we recommend you create live events from the Teams web client in your remote session instead.
- Calls or meetings don't currently support application sharing. Desktop sessions support desktop sharing.
- Give control and take control aren't currently supported.
- Teams on Azure Virtual Desktop only supports one incoming video input at a time. This means that whenever someone tries to share their screen, their screen will appear instead of the meeting leader's screen.
- Due to WebRTC limitations, incoming and outgoing video stream resolution is limited to 720p.
- The Teams app doesn't support HID buttons or LED controls with other devices.
- New Meeting Experience (NME) is not currently supported in VDI environments.

Collect Teams logs
If you encounter issues with the Teams desktop app in your Azure Virtual Desktop environment, collect client logs under %appdata%\Microsoft\Teams\logs.txt on the host VM.
If you encounter issues with calls and meetings, collect Teams Web client logs with the key combination Ctrl + Alt + Shift + 1. Logs will be written to %userprofile%\Downloads\MSTeams Diagnostics Log DATE_TIME.txt on the host VM.
Contact Microsoft Teams support
To contact Microsoft Teams support, go to the Microsoft 365 admin center.
Customize Remote Desktop Protocol properties for a host pool
Customizing a host pool's Remote Desktop Protocol (RDP) properties, such as multi-monitor experience or enabling microphone and audio redirection, lets you deliver an optimal experience for your users based on their needs.
Enabling device redirections is not required when using Teams with media optimization. If you are using Teams without media optimization, set the following RDP properties to enable microphone and camera redirection:
audiocapturemode:i:1enables audio capture from the local device and redirects audio applications in the remote session.
audiomode:i:0plays audio on the local computer.
camerastoredirect:s:*redirects all cameras.
