Microsoft Office was deactived when it should not have been

If Microsoft 365 shows Product Deactivated even though it is paid, the supported fixes are:

1. Sign in again with the account that owns the subscription
   • Open an Office app.
   • Select Sign in or Reactivate if that banner appears.
   • Use the same Microsoft account that was used to buy Microsoft 365.
2. Sign out of all Microsoft 365 apps, then sign back in
   • Close Word, Excel, Outlook, and other Office apps.
   • Sign out.
   • Restart an Office app and sign back in.
3. Check whether the subscription is actually active
   • If the subscription has expired, Office can show activation errors such as Unlicensed Product or We couldn't find any Office products.
   • If the subscription is active but Office still shows deactivated, continue with the sign-out/sign-in or Reactivate steps.
4. Check for multiple Office installations
   • More than one installed copy of Office can cause activation conflicts.
5. If Office came preinstalled on a new device
   • A preinstalled copy may require starting a Microsoft 365 Family trial or buying Office.
   • If not purchasing it, Office on the web can be used instead.
6. If the problem started after a license or subscription change
   • Microsoft documented a known issue where users could randomly receive Product Deactivated after licensing changes.
   • The service-side fix has been deployed, but the recommended workaround is still to select Reactivate or sign out of all Office apps, close them, restart, and sign back in.
7. If the subscription is paid but the app still will not reactivate
   • For home subscriptions, if the install was deactivated or signed out, signing back in reactivates Office.
   • If the wrong account is being used, Office may report that no Office products are found.

If nothing is done, Office eventually runs in reduced functionality mode: documents can still be opened and printed, but editing and creating new files is disabled.

• A subscription notice appears when I open a Microsoft 365 application
• Users might receive a Product Deactivated error in Microsoft 365 Office apps
