FAQs About Fixing a Microsoft 365 Subscription Not Recognized in Word

Why does Word say "Unlicensed Product" even though I paid my renewal fee yesterday?

Billing system updates can take up to 24 hours to sync with local Office cache. To force an update, go to File > Account > Update Options > Update Now, or sign out and sign back in to refresh the license token.

Can having an older version of Office installed cause this subscription error?

Yes. Legacy MSI installations of Office (like Office 2013 or 2016) can create registry conflicts with Microsoft 365 Click-to-Run installations. You must uninstall older versions via the Windows Control Panel and restart your PC before reactivating Microsoft 365.

What should I do if the Microsoft Support and Recovery Assistant (SaRA) fails to fix the issue?

If SaRA fails, the issue is likely a corrupted local network proxy or firewall blocking access to `activation.sls.microsoft.com`. Temporarily disable third-party VPNs or firewalls, then attempt to open Word again.

Does resetting Windows fix a Microsoft 365 subscription not recognized in Word?

Resetting Windows is an extreme and unnecessary measure. Instead of wiping your operating system, perform an Online Repair by navigating to Settings > Apps > Installed Apps, locating Microsoft 365, clicking Modify, and selecting Online Repair.
