why does my excel file now show as an unlicensed product

The warning refers to the Excel application—not the workbook—and the first step is to sign in with the Microsoft account that owns your Office license and confirm that the license is still active.

Check the account and license

1. Open Excel → File → Account.
2. Under User Information, check which Microsoft account is signed in.
3. If it is not the account used to buy or activate Office, select Sign out, close Excel, reopen it, and sign in with the correct account.
4. Open Microsoft’s Services & subscriptions page using that same account.
5. Confirm that Microsoft 365 or your purchased Office edition appears:
   • If the Microsoft 365 subscription is expired or cancelled, renew it and restart Excel.
   • If Office is active, continue with the steps below.
   • If Office is absent, try any other account that may have been used for the purchase or original activation.

Microsoft states that Office displays Unlicensed Product when activation fails; using the wrong account or having an expired subscription are common causes, and editing features may be disabled.^1^

Check for conflicting Office installations

Multiple Office versions can conflict with activation:

1. Close all Office applications.
2. Open Start → Control Panel → Programs → Programs and Features.
3. Search the installed-program list for Office.
4. If more than one edition is installed, uninstall only the version you no longer use.
5. Restart Windows, open Excel, and sign in again.

Do not uninstall your required version. Removing an Office application does not remove your saved Excel workbooks.

Repair Office if the license is active

For Windows 11:

1. Right-click Start → Installed apps.
2. Find Microsoft 365 or Microsoft Office.
3. Select the three dots → Modify.
4. Choose Online Repair → Repair.
5. Restart Windows when it finishes.

For Windows 10, right-click Start → Apps and Features, select Office, and choose Modify → Online Repair → Repair. Online Repair repairs the entire Office suite, even when only Excel shows the problem.^2^

If it remains unlicensed

• Ensure Windows has the correct date, time, and time zone, because incorrect settings can prevent activation.
• If you use Microsoft 365 on Windows 10 or later, run the Microsoft 365 activation troubleshooter from the official activation page on the affected PC.^1^
• If Excel displays an error code, retain the exact code; it identifies the next appropriate activation step.
