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

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)
