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 2x2 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 7x7. 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 more information, see System Requirements. Citrix Workspace app minimum version is required. Starting with Citrix Workspace app for Windows To share a specific app:.
Compatibility with app protection The screen sharing of a specific app is compatible with the app protection feature in HDX optimized Microsoft Teams. You can only select the Window option to share any open app.
This feature is supported in the following versions of Citrix Workspace app there is no dependency on the VDA version or Operative System, single session or multisession :. You can request control during a Microsoft Teams call when a participant is sharing the screen. Once you have control, you can make selections, edits, or other keyboard and mouse activities to the shared screen.
To take control when a screen is being shared, click Request control button in the Microsoft Teams UI. While you have control, you can make selections, edits, and other modifications to the shared screen. Using Teams in a non-persistent setup also requires a profile-caching manager for efficient Teams runtime data synchronization. Efficient data synchronization ensures that the appropriate user-specific information such as a user's data, profile, or settings is cached during the user's session.
Make sure data in these two folders are synced:. A roaming folder or, if you are using folder redirection, a caching manager is required to ensure that the Teams app has the runtime data and files required to run the application.
This is necessary to mitigate network latency issues or network glitches, which would otherwise cause application errors and a slow experience due to unavailable data and files. There are a variety of caching manager solutions available, such as FSLogix.
Consult your caching manager provider for specific configuration instructions. Excluding these items helps reduce the user caching size to further optimize your non-persistent setup. Before you deploy Teams through Microsoft Apps for enterprise, you must first uninstall any pre-existing Teams apps if they were deployed using per-machine installation. Teams through Microsoft Apps for enterprise is installed per-user.
Teams is also being added to existing installations of Microsoft Apps for enterprise. Microsoft Apps for enterprise doesn't support per-machine installations of Teams.
To use per-machine installation, you must exclude Teams from Microsoft Apps for enterprise. To learn more about Teams and Microsoft Apps for enterprise, see How to exclude Teams from new installations of Microsoft Apps for enterprise and Use Group Policy to control the installation of Teams. At this point, the golden image setup is complete. This process adds a required registry key to the machine that lets the Teams installer know it is a VDI instance.
Without it, the installer will error out, stating: "Installation has failed. Cannot install for all users when a VDI environment is not detected. All users can then uninstall Teams if they have admin credentials. PowerShell script : You can use the Teams deployment cleanup PowerShell script to uninstall Teams and remove the Teams folder for a user.
Run the script for each user profile in which Teams was installed on the computer. There are a variety of virtualized setup configurations, each with a different focus for optimization. For example, a configuration might focus on user density. When planning, consider the following to help optimize your setup based on your organization's workload needs.
In addition to chat and collaboration, Teams on VDI with calling and meetings is available with supported virtualization provider platforms. Supported features are based on the WebRTC media stack and virtualization provider implementation. The following diagram provides an overview of the architecture. If you currently run Teams without AV optimization in VDI and you use features that are not supported yet for optimization such as Give and take control when app sharing , you have to set virtualization provider policies to turn off Teams redirection.
This means that Teams media sessions won't be optimized. For steps on how to set policies to turn off Teams redirection, contact your virtualization provider. We recommend that you evaluate your environment to identify any risks and requirements that can influence your overall cloud voice and video deployment. How to do it is fairly simple described in Microsoft documentation. Download the MSI installer and run this silent installation command:. Since the Horizon client 5. Save my name, email, and website in this browser for the next time I comment.
May 12, by Michal Minarik 1 Comment. With per-user installation, automatic updates is enabled. For most VDI deployments, we recommend you deploy Teams using per-machine installation. To update to the latest Teams version, start with the uninstall procedure followed by latest Teams version deployment. This makes complete sense for a VDI environment.
They found a series of laptops that would not update to the latest Teams client no matter what they did. The only recourse was to uninstall and reinstall the client. This credit goes to one our engineers, Jeremy Coleman, who did all of the hard work of tracking down what was happening. That entry may also have a value of 1, either case indicates you are in VDI mode. If it does not exist or has the value of 0, you are not in VDI mode.
To get to the diagnostic logs, you can follow the steps laid out in the Microsoft Docs.

Microsoft Business. Microsoft Enterprise. VMware strongly recommends using the officially supported versions. For beta testing, VMware published the Horizon Client beta installer for Mac via the beta portal that supports optimization.
VMware recommends that you use the officially supported version, Horizon Client or later for Mac, to get the latest functionality and bug fixes for the Mac client. Similarly, VMware published a beta version of Horizon Client for Linux that supports optimization via the beta portal.
VMware recommends using the officially supported version, Horizon Client or later for Linux, to get the latest functionality and bug fixes for the Linux client.
The ports described on that page are required to be opened on the client device. Note : The usual Horizon ports are also required, as detailed in the following documents:. Some organizations might require that the process name of the Teams Optimization Pack be added to a firewall allowlist, to allow communication to the Microsoft Teams Cloud server.
The process name is vmware-remotemks. This is a Microsoft restriction. In certain low-powered clients, users may want to turn off software acoustic echo cancellation to reduce CPU usage. In most cases, VMware recommends using the default configuration, which is designed for optimal audio experience. But if you are having issues with echo, software acoustic echo cancellation can be configured by using a GPO on the Horizon Agent or by setting a registry key on the Horizon Client.
Note that this configuration is only supported on Windows Clients. After setting this policy, you must log out of the Horizon desktop for the GPO policies to take effect. This configuration can also be applied on the Horizon Client for Windows device by setting the following registry key:. To troubleshoot, start by checking whether Microsoft Teams launched in optimized mode and whether the correct local client device names are being picked up.
If so, you can check whether the Microsoft Teams redirection plugin has been installed and check the logs to verify that optimization has been enabled. Procedures for these tasks are described in the following sections:. Figure 9: Version Box for Microsoft Teams. If the registry key is not set, follow the installation guidance for Horizon Agent, as described in Horizon Agent Installation and Configuration.
Also note that you need to log out of the Horizon desktop for the GPO policies to be applied. In the virtual desktop, restart Microsoft Teams to ensure that the correct settings have been applied by the Microsoft Teams client. We have seen issues in Microsoft Teams where incorrect flags get applied. Restarting Teams ensures that the correct flags are pulled in and applied.
Quit the Microsoft Teams application. This will force Microsoft Teams to reload its cache, which may have contained outdated values related to the environment. To ensure that Microsoft is not detecting a conflicting Citrix Agent installation on the desktop, review the Microsoft logs.
Instructions for collecting Microsoft logs are provided in the Microsoft documentation topic Use log files to monitor and troubleshoot Microsoft Teams. In Microsoft Teams, click the ellipsis points … next to your profile picture at the top, and then select Settings and go to the Devices section.
Under Audio devices , you should see the local headset names in the Speakers and Microphone drop-down lists. Figure Device Settings for Microsoft Teams. If you see the local device names in the Microsoft Teams device settings, then Microsoft Teams optimization has been enabled in your environment. Check if html5Server. 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.

You can request control during a Microsoft Teams call when a participant is sharing the screen.
Audio does not have to double hop between end-device, VDI, and Teams servers but instead goes directly to Teams servers. Also, audio and webcam video are not rendered in the VDI reducing resource utilization. Mapping of audio and webcam devices functions more natively without leveraging VDI vendor technologies, such as Citrix HDX audio, which can be buggy. The pace with which versions are released provides a significant operational requirement to stay up to date.
End-client agent versions must be released by vendor and then updated on the end-device. The Teams version in the VDI must also be updated if per-machine installed. If thin-clients are used as end devices, the updates can be further delayed as the vendor agents are typically included as part of the thin-client OS.
This means operations must validate and deploy new OS versions of thin clients as well as testing in VDI. Features are limited, as defined in section below. Unoptimized Pros: Almost the full feature set of Teams as compared to physical device install. Teams functions the same way as all other conferencing tools, such as WebEx, reducing user confusion.
Unoptimized Cons: Audio and video performance is reduced and heavily dependent on the end-device and VDI network stability. Any latency or bandwidth issues are compounded due to the double hop between device, VDI, and Teams servers. Audio and video device instability causes users to have to restart Teams, and sometimes the VDI session itself, to continue working after crashing.
