Update – 28 November 2022 – Check out this blog for a better way to remove the Windows 11 built in Teams app
With Windows 11, Microsoft Teams is now available as a built in app… which is great!
But at the time of writing this post, you cannot use the Microsoft Teams built-in app with a Work or School account… not great.
Many business managed devices that have been upgraded to Windows 11 will also still have the Teams Machine-Wide Installer version of Microsoft Teams, resulting in the user the experience of two versions of Microsoft Teams in the Start Menu.

At this stage, only the Teams Machine-Wide Installer version of Microsoft Teams can be used, so having the built-in version present along side it with the same name could cause some confusion. To get around this, I will use the Intune PowerShell Scripts feature.
The PowerShell script contains the following command:
Get-AppxPackage "*Teams*" -AllUsers | Remove-AppPackage -AllUsers
I have added this script to Intune and deployed to my Azure AD Dynamic Device group Device – Win 11 – All Managed Windows 11 (unfortunately Intune Filters are not available for PowerShell Script deployments)

Once the script has run on the device, the built-in Microsoft Teams app will be removed.

This may take a bit of time to deploy to devices that have recently been in-place upgraded to Windows 11, but the app will be removed eventually.
I’m hoping Microsoft provide a way to easily re-add this app later (The Microsoft Store would be ideal) as I can see the benefit of replacing the deployed Teams Machine-Wide installer with this version once it can be used with Work or School Azure AD account
P.
thank you

I am so tired and demoralized, I tried your method step by step, and it did not work on Windows 11. What could I have been doing wrong?
