Activation

Follow these steps in order on the same PC where Microsoft 365 is installed:

1. Confirm the correct account and subscription status
   • Close all Office apps.
   • Go to the Microsoft account Subscriptions page: https://account.microsoft.com/services
   • Sign in with the @comcast.net account used to purchase Microsoft 365.
   • Under Subscriptions (and Cancelled subscriptions), verify that the Microsoft 365 subscription is listed as active, not expired or cancelled.
   • If it shows as expired or cancelled, renew it following the steps in Renew Microsoft 365 Family, then restart Word and check activation again.
2. Make sure Word is signed in with the same account
   • Open Word.
   • Go to File → Account.
   • Under User Information and Product Information, ensure the signed-in account matches the @comcast.net account that owns the subscription.
   • If a different account is shown, sign out, then sign back in with the correct account and select Update license (or similar) if available.
3. Run the Microsoft 365 activation troubleshooter
   • On Windows 10 or later, run the Microsoft Support and Recovery Assistant for activation:
     • Use the Start button in the article Office error "Account Notice: We've run into a problem with your Microsoft 365 subscription" or Unlicensed Product and activation errors in Office.
     • When prompted, click Open to allow Get Help to start.
     • Run it on this same PC and follow all prompts to detect and fix activation issues.
4. If still not activating, fully reinstall Office If activation still fails after the troubleshooter:
   • Deactivate the current install for this device using the steps in Deactivate a Microsoft 365 install (linked from the same activation error article).
   • Completely uninstall Office using the easy fix tool described in Uninstall Microsoft 365 from a PC.
   • Reinstall Microsoft 365 following Download, install, or reinstall Microsoft 365 or Office 2024 on a PC or Mac.
   • After reinstall, open Word, sign in with the @comcast.net account, and confirm activation.
5. If the subscription itself is in trouble (billing issue)
   • If, instead of “Unlicensed Product”, a banner like “ACCOUNT NOTICE. We've run into a problem with your Microsoft 365 subscription and need your help to fix it.” appears, this usually indicates a payment or billing problem (expired or declined card, suspended subscription).
   • In that case, fix the payment method and renew/restore the subscription from the Subscriptions page, then restart Office.

If none of these steps resolve the issue and the subscription is confirmed active under the correct account, contact Microsoft support and reference that all standard activation and reinstall steps from the activation error articles have already been completed.
