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!

I was able to get it working with 2019. I'm using Citrix App layering 24.3.2.1021

Be sure to have the latest release of Fslogix, 2.9.8884.27471, it using it as a profile manager

I went to VDA2403 so I didn't have to create the registry key ProcessWhitelist as its now included in the VDA

You also need to enable Side load by enabling "Allow all trusted apps to install". I enabled this in my platform layer but also added it to Group Policy.

if you want to enable presence in outlook there are some additional steps but these are the basic steps i used first.

I can agree that the release of a working fslogix did not give users a whole lot of time to move a working product to production.
