- Product
- Microsoft 365 (Word, Excel)
- Device & OS
- Windows 11
- Scenario
- Attempting to activate or use Microsoft 365 applications after installation.

Verify Subscription and Reinstall Microsoft 365
Checking your active subscription status and performing a clean reinstallation using the official Microsoft support tool typically resolves corrupted login state issues.
This issue is often caused by corrupted local credential caches or incomplete installation files that prevent the authentication service from loading the password prompt.
Navigate to https://account.microsoft.com/services in your web browser and log in to verify that your Microsoft 365 subscription is active.
If the subscription is active, visit the official Microsoft Support page to download the Office uninstall support tool.
Run the downloaded uninstall tool and follow the on-screen prompts to completely remove all Microsoft 365 applications and cached files from your Windows 11 PC.
Restart your computer, log back into your Microsoft account dashboard, and download a fresh installer to reinstall Microsoft 365.
