This section provides recommendations and guidance to estimate how many users or virtual machines VMs can be supported on a single physical host. The idea is to find out how many users or VMs can be ran on a single piece of hardware running a major hypervisor. This section includes guidance to estimate SSS. Note that the guidance is high level and might not necessarily be specific to your unique situation or environment. Citrix recommends using this guidance and these simple rules to quickly estimate SSS only.

However, Citrix recommends using Login VSI or the load testing tool of your choice to validate results, especially before purchasing hardware or making any financial decisions. To enable optimization for Microsoft Teams, use the Manage console policy described in the Microsoft Teams redirection policy.

This policy is ON by default. In addition to this policy being enabled, HDX checks to verify that the version of the Citrix Workspace app is at least the minimum required version. Microsoft Teams reads the key to load in VDI mode. Loading the API is the first step toward redirection. Exit Microsoft Teams by right-clicking the notification area icon and restarting.

Microsoft Teams relies on Media Processor servers in Microsoft for meetings or multiparty calls. So the network health between the peer and the Microsoft cloud determines the performance of the call.

Please refer to Microsoft network connectivity principles for detailed guidelines around network planning. We recommend evaluating your environment to identify any risks and requirements that can influence your overall cloud voice and video deployment. For support information, see Support. The manner in which this is accomplished will vary depending on the VPN product and machine platform used but most VPN solutions will allow some simple configuration of policy to apply this logic.

For more information on VPN platform-specific split tunnel guidance, see this Microsoft article. Citrix minimum recommendations per user are:. About performance, encoding is more expensive than decoding for CPU use at the client machine. You can hardcode the maximum encoding resolution in the Citrix Workspace app for Linux and Windows.

See Encoder performance estimator and Optimization for Microsoft Teams. If you configure an explicit proxy server in the VDA and route connections to localhost through a proxy, redirection fails. If not, optimization fails. If the branch office is configured to access the internet through a proxy, these versions support proxy servers:. If DNS requests are unsuccessful, P2P calls with outside users and conference calls media establishment fails.

This support means that the endpoint must be able to perform DNS resolutions. Consider a scenario where there is no direct path between the two peers or between a peer and a conference server and you are joining a multi-party call or meeting.

The HdxRtcEngine. These ranges include both Transport Relays and media processors, front-ended by an Azure Load Balancer. Call quality depends on the underlying network protocol. Meetings fail. Use this architecture diagram as a visual reference for the call flow sequence. The corresponding steps are indicated in the diagram.

Citrix media engine and Teams. With Direct Routing, you connect your own supported session border controller to the Microsoft Phone System directly without any additional on-premises software.

Call queues, transfer, forward, hold, mute, and resume a call are supported. Starting with version , Citrix Workspace app supports dynamic emergency calling. The notification is provided based on the current location of the Citrix Workspace app that runs on the endpoint, instead of the Microsoft Teams client that runs on the VDA. To enable dynamic emergency calling, the administrator must use the Microsoft Teams Admin Center and configure the following to create a network or emergency location map:.

When users start an optimized call using the Microsoft Teams client for the first time, they might notice a warning with the Windows firewall settings.

The warning asks for users to allow communication for HdxTeams. You can apply more restrictive rules if you want. You can deploy Microsoft Teams and Skype for Business side by side as two separate solutions with overlapping capabilities.

For more information, see Understand Microsoft Teams and Skype for Business coexistence and interoperability.

Examples include island modes and Skype for Business with Microsoft Teams collaboration. Also, Skype for Business with Microsoft Teams collaboration and meetings. Peripheral access can be granted only to a single application at the time. For example, webcam access by the RealTime Media Engine during a call locks the imaging device during a call.

When the device is released, it becomes available for Microsoft Teams. Optimal audio and video quality require a network connection to the Microsoft cloud that has low latency, low jitter, and low packet loss. Backhauling of Microsoft Teams audio-video RTP traffic from Citrix Workspace app users at branch office locations to a data center before going to the internet can add excessive latency. It might also cause congestion on WAN links. This use is to identify, categorize, and steer Microsoft Teams traffic.

Business broadband internet connections in many areas suffer from intermittent packet loss, periods of excessive jitter, and outages. You can use multiple meetings or chat windows for Microsoft Teams in Windows.

This feature is supported with Citrix Workspace app for Windows Microsoft Teams supports Gallery , Large gallery , and Together mode layouts. Microsoft Teams displays a 2×2 grid with video streams of four participants known as Gallery. In this case, Microsoft Teams sends four video streams to the client device for decoding. When more than four participants share video, only the last four most active speakers appear on the screen.

Microsoft Teams also provides the large gallery view with a grid up to 7×7. As a result, the Microsoft Teams conference server composites a single video feed and sends it to the client device for decoding, resulting in lower CPU consumption. Lastly, Microsoft Teams supports Together mode , which is part of the new meeting experience. Using AI segmentation technology to digitally place participants in a shared background, Microsoft Teams puts all participants in the same auditorium.

The user can control these modes during a conference call by selecting Gallery , Large gallery , or Together mode layouts in the ellipses menu. Microsoft Teams relies on video-based screen sharing VBSS , effectively encoding the desktop being shared with video codecs like H and creating a high-definition stream. With HDX optimization, incoming screen sharing is treated as a video stream.

Starting from Citrix Workspace app or higher for Windows, Linux or Mac, users can share their screens and video camera simultaneously. Instead, the screen sharing video feed shows. The peer must then manually resume the camera sharing. In that case, other peers can still see your webcam and content and navigate back and forth to review other slides. In this scenario, the slides are rendered on the VDA. Outgoing screen sharing is also optimized and offloaded to Citrix Workspace app.

Set specific permission in Citrix Workspace app for Mac to enable screen sharing. For example, Citrix optimization was only available when deploying on the system drive. But with a recent patch, this was no longer true, and Teams automatically switched to Citrix optimization mode, which has limited features.

These types of issues result in a significant number of help desk calls until a workaround could be implemented. In early , it was recommended to install per-user as it allowed preventing Teams from auto-starting.

This let users who were not interested in Teams not have it launch and reduced the infrastructure resource requirements of every user having a Teams session.

However, as Covid precautions stuck around and adoption drastically increased, it no longer made sense to allow per-user installs to persist and provide inconsistency in the environment. The migration from per-user to per-machine is automatic. Microsoft will convert the install when a per-user logs into a per-machine image. We noticed that the Taskbar shortcut must be unpinned and repined as it still pointed to per-user install. Also, the Teams Outlook add-in pointed to the old per-user install and had to be fixed with a registry key update.

And finally, on rare occasions, the migration did not work successfully; In the session as an admin, Teams had to be uninstalled and then reinstalled. Pros and cons of per-machine and per-user installments:.

How many end devices are needed is largely dependent on whether optimization will be enabled see section below. If unoptimized, the end-device is less important as most of the computation occurs in the VDI. H owever , all audio and webcam must still traverse the network to the VDI.

This can provide a wide disparity in end-user experience if a standard is not implemented. This increases outbound network load to the internet for your branch sites. Microsoft has worked together with virtual desktop vendors, such as Citrix and VMware, to implement an optimized mode of Teams. This enables H. While significantly improved over , there are still feature limitations in the optimized version of Teams.

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.

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. 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.

For Teams known issues that aren’t related to virtualized environments, see Support Teams in your organization. To contact Microsoft Teams support, go to the Microsoft admin center.

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 isn’t required when using Teams with media optimization. If you’re using Teams without media optimization, set the following RDP properties to enable microphone and camera redirection:. Similarly, if you are using a. Otherwise, html5server will not work as expected.

Because html5server. This is an internal registry key used by html5Server. Backing up and restoring the registry key may result in erroneous behavior. If you do not have any user profile management software installed or have excluded the above-mentioned registry key from the list, follow the next action item.

Important : For the following step, you need to have administrator privileges on your virtual desktop operating system. If you see the below highlighted section, then Microsoft Teams optimization has been enabled on your VM. Note : For your convenience, the highlighted text you can search for includes the following settings:.

If the above settings are missing from the logs or if the logs display “allow:false” then Microsoft Teams optimization has not been enabled in your environment. Go through the installation guidance for Horizon Client for Windows or Linux, as described in Client Installation , and ensure that Media Optimization for Microsoft Teams check box has been selected in the Horizon Client Installation wizard.

For the Mac platform, ensure that you have the supported version of Horizon Client installed. If you have the supported versions installed and have selected the right configuration for Media Optimization for Microsoft Teams, contact VMware support.

If you see the below highlighted section in the logs, then Microsoft Teams optimization has been correctly enabled for your session. If the above settings are missing from the logs or if the logs display “allow”:”false” then Microsoft Teams optimization has not been enabled in your environment. Contact VMware for further assistance. If Microsoft Teams on VDI is optimized and you are running into generic issues, or if you find that features are missing, check if you see the same behavior when using the Microsoft Teams web client.

If you see the same behavior on the web client, or if you find that a feature is missing, contact Microsoft for further assistance. This section describes how to collect logs from the virtual desktop, the client device, and the Microsoft Teams app. The improved end-user experience, decreased load on the data center, and decrease in network traffic make Media Optimization for Microsoft Teams a compelling feature. A thoughtful rollout plan will keep users productive. See the Microsoft Documentation for details about Microsoft Teams installation, performance considerations, and feature limitations.

See the VMware Horizon Documentation for details about supported features and limitations. This message will close in seconds. You are about to be redirected to the central VMware login page. Minimum Supported Horizon Client Versions Horizon supports audio, video, and screen-sharing offload to the local endpoint on Windows, Mac, and Linux platforms. Horizon 7. System Requirements This section briefly lists the system requirements for both the client and the virtual desktop when using the Media Optimization for Microsoft Teams feature.

Pairing Modes As described in the overview of this guide, there are significant advantages to running Microsoft Teams in optimized mode. Fallback mode has the same limitations as optimized mode.

Microsoft is continuously adding features. For the latest supported features list, see the Microsoft document Teams for Virtualized Desktop Infrastructure.

You can also try running Microsoft Teams from within a Chrome browser, which will give you an idea of the available functionality.

If you have full-clone persistent desktops, can you apply the GPO to only those users who will be able to run in optimized mode?
