Question details

The user is encountering continuous authentication prompts and licensing failures in Microsoft 365 Family, even after renewing the subscription.

How to Fix Microsoft 365 Authentication and Licensing Loops

Product: Microsoft 365 Family
Device & OS: Windows
Scenario: Using Microsoft 365 desktop applications after a subscription renewal or account change.
Observed behavior: Office repeatedly requests authentication, fails to validate the active subscription, and displays an unlicensed product error, disabling desktop features like VBA.

Before you start

Ensure you know the exact Microsoft account email and password associated with your active Microsoft 365 Family subscription. Save your work and close all open Office applications before modifying system credentials.

Solution 1Recommended

Clear Outdated Office Credentials from Windows

Removing old or corrupted Office credentials from the Windows Credential Manager forces Office to request a fresh authentication token and validate your renewed subscription.

Authentication loops often occur when Windows caches an expired login token. By clearing these generic credentials, you allow Microsoft 365 to establish a new, secure connection to the licensing servers.

Close Office Applications

Sign out of your account inside any Office app if possible, then completely close all Microsoft Office applications running on your device.

Open Credential Manager

Click the Windows Start button, type 'Credential Manager' into the search bar, and press Enter to open the utility.

Locate Generic Credentials

Click on 'Windows Credentials' and scroll down to the section labeled 'Generic Credentials'.

Remove Office Entries

Find any entries that start with 'MicrosoftOffice', click on them to expand the details, and select 'Remove'. Confirm the deletion.

Restart and Sign In

Restart your computer, open a desktop app like Word, and sign in again with the Microsoft account that owns the Microsoft 365 Family subscription.

Clear Outdated Office Credentials from Windows

Restored Features: Once authenticated properly, previously disabled desktop features like VBA macros will be fully restored.

Solution 2

Reinstall Microsoft 365 Desktop Applications

If clearing credentials does not resolve the licensing loop, reinstalling Office will replace corrupted installation files and reset the licensing state.

Frequently Asked Questions

Why does Microsoft 365 keep asking me to sign in?

This usually happens when there is a conflict or corruption in the cached credentials on your device. Clearing the Generic Credentials in Windows Credential Manager forces a fresh sign-in and often resolves the issue.

Will clearing my Windows credentials delete my Office documents?

No, clearing Windows credentials only removes the stored login tokens used to authenticate your Microsoft applications. Your personal files, documents, and application settings remain completely untouched.

Why does Office say 'unlicensed product' after I renewed my subscription?

The desktop applications may still be trying to use an expired cached token instead of retrieving your updated subscription status from Microsoft's servers. Signing out, removing old credentials, and signing back in refreshes your license state.

Can I still use Office Online if my desktop apps are locked in an authentication loop?

Yes, Office Online runs through your web browser and relies on your current web session. As long as your subscription is active, you can access web versions of Word, Excel, and PowerPoint even if desktop apps fail to authenticate.
