Fixing Microsoft 365 License Assigned but App Unlicensed

If your Microsoft 365 app shows as unlicensed after a Windows update, it usually means there is a synchronization issue with your Microsoft account or changes to settings from the update. You can quickly fix this by following some troubleshooting steps to reactivate your license.

Why is my Microsoft 365 app unlicensed after a Windows update?

This issue may happen for several reasons. Following a Windows update, the app might not recognize your license due to sync problems between your Microsoft account and the Office application. Updates can change user account settings or group policies that affect licensing. Sometimes, the app may need manual reactivation.

Before you start

Make sure you have a stable internet connection and are signed in to the Microsoft account that holds the license. Verify that your Office applications are updated to the latest versions available as of 2026.

How to verify your Microsoft 365 license status

To check if your Microsoft 365 license is active, follow these steps:

1. Open any Office app, like Word or Excel.
2. Click on File in the top-left corner.
3. Select Account from the menu.
4. Look for the Product Information section to see your license status.

If it shows 'Product Activated' with your account listed, your license is active.

Step-by-step troubleshooting guide

If your app is showing as unlicensed, try these steps to fix it:

1. Sign out and back in: - In any Office app, go to File > Account > Sign Out. Then sign back in with your Microsoft account.

2. Check for updates: - Go to the Account section and click on Update Options > Update Now. This ensures your Office apps are current.

3. Reactivate the app: - In the app, go to File > Account > Change Product Key and enter your product key if prompted.

4. Repair Office: - Go to Control Panel > Programs and Features. Right-click on Microsoft 365 and choose Change, then select Quick Repair.

5. Reinstall Office (if issues persist): - Uninstall Office from Programs and Features and then reinstall it from your Microsoft account.
