Installing or updating the Teams app for education users across supported platforms
The message that the new or updated Teams is “blocked by admin” means organization policies are preventing installation of the Teams MSIX package.
To resolve this, an IT admin must adjust policy/registry settings or update Windows:
- Ask the IT admin to check Group Policy
- Open Local Group Policy Editor (
gpedit.msc). - Go to: Computer Configuration > Administrative Templates > Windows Components > App package Deployment.
- Ensure these policies are set to Not configured:
- Prevent non-admin users from installing packaged Windows apps
- Allow all trusted apps to install
- Open Local Group Policy Editor (
- Check registry keys that can block Teams MSIX installation
The following keys can block installation if configured by policy or a management tool:
-
BlockNonAdminUserInstall -
AllowAllTrustedApps -
AllowDevelopmentWithoutDevLicense
-
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AppModelUnlock -
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Appx
- If AllowAllTrustedApps is disabled, new Teams installation fails. This is fixed in the Windows October cumulative updates KB5031445 (Windows 10) and KB5031455 (Windows 11), or later security updates. Ensure the device has these or newer updates installed.

- If policies are intentionally restrictive
- Only the organization’s admin can relax or change these settings. If the message says “Due to org policy, you can’t install the new Teams. For more info, contact your IT admin,” the correct action is to contact the IT admin and request that Teams installation be allowed.
Once the blocking policies/registry settings are corrected and Windows is updated (if needed), downloading and installing the updated/new Teams on the PC should succeed.
