Hi @AmazingPhone6248
- You can try to let users clear Teams cache after updating the policy.
- If clearing the cache has no effect, please try downloading New Teams directly from the Teams official website.
- According to the documentation: It's possible that the MSIX package installation could be blocked by registry keys set by GPO policy/third party tool. For a complete list of registry keys: How Group Policy works with packaged apps - MSIX
The registry keys that could block new Teams MSIX package installation are:
- BlockNonAdminUserInstall
- AllowAllTrustedApps
- AllowDevelopmentWithoutDevLicense
These registry keys can be found at one of these locations:
- Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AppModelUnlock
- Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Appx
Please check this setting for your computer:
