Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Dear @Vicar Kuria
To fix the error where Office cannot verify the product license via Control Panel, you can repair Microsoft 365 directly through Windows Settings or using the official command-line version of Get Help.
Here are the step-by-step methods to resolve this issue:
Method 1: Perform an Online Repair via Windows Settings
An Online Repair replaces corrupted licensing files and ensures Office properly verifies your subscription with Microsoft servers.
- Close all open Office applications.
- Right-click the Start button and select Installed apps (or Apps & Features in Windows 10).
- Scroll down and locate Microsoft 365 (or Microsoft Office).
- Click the three dots menu next to it and select Modify.
- Select Online Repair, then click Repair and follow the on-screen instructions.
- Once completed, restart your PC, open Word or Excel, and sign in with the Microsoft account associated with your license.
For additional official step-by-step guidance, you can refer to the Microsoft Support page on Repairing an Office Application.
Method 2: Reset the Office Activation State
If repairing Office does not fix the verification issue, clearing cached activation credentials usually resolves underlying licensing errors:
Sign out of all Office apps and close them.
- Open Control Panel > User Accounts > Credential Manager.
- Select Windows Credentials.
- Look under Generic Credentials for any entries containing MicrosoftOffice16_Data or SSO_POP_Device and click Remove.
- Reopen Word, sign back in with your account, and allow Office to reactivate.
Method 3: Use the Official Microsoft Support Tool
If the issue persists, Microsoft provides the command-line version of Get Help to automate checks and reset Office activation state: Command line version of Get Help
