Overview

This article provides guidance for running Microsoft Teams in the Evolve IP Cloud Services.  Specifically, our Workspaces (Citrix) offerings, and our VMware Horizon Desktop as a Service (DaaS) products.

MS Teams and Workspace

Evolve IP Workspaces Products

Workspaces Desktop	RTAV Support	Microsoft Certified	Optimized for MS Teams	Important Notes
Workspaces Std	NA	NA	NA	Workspaces Standard does not include a desktop for MS Teams, and we do not support wrapping MS Teams as a deliverable app.
Workspaces Pro				Workspaces Pro does not meet the minimum requirements to support MS Teams when real-time audio/video calls and meetings are enabled.  This desktop can be used for all other features in MS Teams.
Workspaces Elite				Workspaces Elite supports all MS Teams features.

Some Possible Feature Limitations

• It's important to point out that high video resolutions put a load on the virtual desktop's vCPUs.  Therefore, clients need to understand that when MS Teams is used in a virtual desktop for audio/video calls and meetings, the virtual desktop's performance will take a major hit when running high video resolutions.
• Depending on the virtual environment, only a single incoming video stream may be supported in meetings or group calls.  When there are multiple participants sending their video, only the dominant speaker’s video is shown at any time. 
• Users may not be able to enable screen sharing during a chat session.  If that's the case, the user has to start an audio/video call before screen sharing will work.
• When doing screen sharing in multi-monitor setups, it's possible the user's main monitor is only shared.
• During screen sharing, give control take control may not be supported.

Important Terminology

Optimized for MS Teams - This means the virtual desktop environment, the endpoint device connecting to the virtual desktop, and MS Teams installed in the virtual desktop has been fully optimized to support real-time audio/video calling and meetings in MS Teams.

Unoptimized for MS Teams - This means MS Teams has been installed in a virtual desktop environment without any optimizations.

Real-Time Audio/Video (RTAV) - A delivery mechanism between the virtual desktop and the endpoint device that facilitates MS Teams audio/video calling and meetings.  Each virtual environment vendor (Microsoft, Citrix, & VMware) have developed their own technologies to support RTAV.

Microsoft's Guidance for MS Teams in Virtual Environments

Microsoft's guide for running MS Teams in a Virtualized Desktop Infrastructure (VDI) environment is very comprehensive, and it should be a client's starting point for understanding the ins and outs of running MS Teams in a virtual environment.  The client should pay close attention to the following parts of the guide:

• MS Teams installation and upgrade requirements
• The MS Teams performance considerations
• Known issues and limitations

MS Teams in Workspaces (Citrix)

Some highlights and information about Workspaces as it relates to MS Teams:

• Currently, Citrix is the only virtual environment that is certified by Microsoft for MS Teams.  This means Citrix has developed their environment to support the MS Teams "optimized" mode.
• When MS Teams is optimized for a virtual desktop environment, the environment can handle real-time audio/video (RTAV) features, as long as the minimum requirements are met.
• Only the Workspaces Elite desktop can support MS Teams optimized RTAV features.
• The Workspaces Pro desktop is only able to support MS Teams when the RTAV features are disabled.  In other words, audio/video calls and meetings are not supported.
• The Citrix Optimization Guide for Microsoft Teams is a public guide that outlines all of the requirements for configuring the virtual desktop environment (EIP responsibility), and the endpoint devices accessing a virtual desktop (client responsibility).  The optimization guide includes the following:
  • Minimum endpoint requirements (hardware, operating systems, and software)
  • Recommended peripherals (headsets & webcams).
  • A list of supported thin clients from multiple vendors.
  • Network considerations, and call flow information.
  • Known limitations, and some troubleshooting information.

MS Teams in VMware Horizon DaaS

Some highlights and information about VMware Horizon DaaS as it relates to MS Teams or any RTAV collaboration software (Skype, Zoom, Webex)

• Microsoft Teams with Real-Time Audio-Video is supported on Horizon Agent 7.9 and later on Windows, Linux, and Mac clients.
• Currently, VMware Horizon DaaS is not "certified" by Microsoft (like Citrix) for MS Teams.  
• VMware's minimum requirements for running MS Teams with real-time audio/video (RTAV) is 4 vCPU and 4 GB RAM. 
• The product, engineering, and proserv teams are currently testing our DaaS Premium & Ultimate Seats to see if they can handle MS Teams with RTAV features enabled.
• Our engineering team is currently looking into the ability to offer virtual desktops with 4 vCPUs.  No ETA at this time.
• Minimum requirements and additional information can be found in VMware's public guide: Configuring MS Teams for real-time audio/video.
• RTAV not supported on WYSE thin clients at this time.  WYSE is planning a future update to thinOS to provide better support for RTAV.
