How do I get a stable New Teams install on a 2019 Server running a Citrix VDA?

Question

Hello, everyone!

I've gone through all of these requirements on a fresh install of Server 2019:

I have the correct .msix x64 Teams file. I am getting the following errors using the bootstrap installer:

Using another forum post, I tried this command:

powershell.exe -ExecutionPolicy bypass -command "&{ Add-AppxProvisionedPackage -Online -PackagePath .\MSTeams-x64.msix -SkipLicense }"

...which resulted in this:

Add-AppxProvisionedPackage : error C00CE014: App manifest validation error: The app manifest must be valid as per
schema: Line 20, Column 6, Note: The schema for MaxVersionTested specified does not recognize XML fields with

Any Suggestions? Thanks in advance!

Hi @Steve Hurd

The following minimum versions are necessary to support the new Teams client:

Citrix Workspace app:

• Windows 2203 LTSR (and any CU)
• Windows 2302 CR
• Linux 2207
• Mac 2302
• Chrome/HTML5 2301

Citrix Virtual Delivery Agent (VDA):

• 1912 CU6 (and any subsequent CU)
• 2203 LTSR (and any CU)
• 2212 CR

In addition, you must deploy the following registry key on the VDA for the new Teams client to be optimized:

• Location:  HKLM\SOFTWARE\WOW6432Node\Citrix\WebSocketService
• Key (REG_Multi_SZ): ProcessWhitelist
• Value: msedgewebview2.exe

Are you using FSLogix for profile management? https://learn.microsoft.com/en-us/fslogix/overview-what-is-fslogix

Are you using persistent or non-persistent images? Are these on Prem or hosted in Azure?

How are users connecting to VDI (Cloud Gateway, SSL on prem etc) Are these on Prem or hosted in Azure?

Are you using Cached user Profiles (Kills Teams)

Answer 3

• Run this command: Dism /Online /Add-ProvisionedAppxPackage /PackagePath:MSTeams-x64.msix /SkipLicense
• MSTeams-x64.msix should be in the same directory in which you are running the command from.

Hi All, has anyone installed the new MS Teams into a pvs environment (win 2019)?
I am using the following command and the new Teams can be installed successfully:
Dism /Online /Add-ProvisionedAppxPackage /PackagePath:<MSIX package path> /SkipLicense

Based on this article:
https://learn.microsoft.com/.../new-teams-vdi...

The Teams opens on the MTD, but as soon as i create an image and assign to the VDAs, the Teams app cannot be opened. In eventlog can be seen:
Failure to instantiate storage folder C:\Users\NAME\AppData\Local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache for package MSTeams_8wekyb3d8bbwe with Error Code: -2147024809 Any suggestion?
Thanks!

So with not long to go now before the great Teams Classic expiry, has anyone got a step-by-step iron-clad method and components for installing New Teams, successfully on a 2019 Server Citrix VDA, where it opens for a user and works hunky dory with HDx Optimisation. I was hoping James Rankin would have made an article, as they are normally the answer, but getting it on 2019 server doesn't doesn't seem to have been thought about and good ol' MS are once again not making enterprise lives easy.

No side-by-side, just a fresh install, imagine it's a virgin 2019 server with the the Citrix VDA / Workspace components. What is the working method of New Teams.
