    Since Copilot in Word suddenly stopped working, use these checks and fixes in order:

    1. Confirm the right account is signed in
      • In Word, look at the account shown at the top-right of the window.
      • Ensure it is the Microsoft account that has an active Microsoft 365 subscription with Copilot (for home users: Microsoft 365 Personal or Family, or Copilot Pro).
      • If another account is listed as primary, switch to the licensed one or sign out of unneeded accounts, then restart Word.
    2. Make sure Office is fully updated
      • In Word, go to File > Account.
      • Under Office Updates, install any available updates.
      • Close and reopen Word after the update completes.
    3. Refresh the Copilot license in Word (Windows)
      • In Word, go to File > Account.
      • Select Update License.
      • Close all Office apps (Word, Excel, PowerPoint, Outlook), then reopen Word and test Copilot again.
    4. Check for common causes if Copilot is missing or disabled
      • If the Copilot button is missing or greyed out, typical causes include:
        • Newly assigned license that hasn’t fully propagated yet.
        • Being signed in with both personal and work/school accounts, which can cause license validation conflicts.
        • Internet or network issues that block Copilot’s required endpoints.
        • Using a channel that doesn’t support Copilot (for organizations, Semi-Annual Enterprise Channel is not supported).
      • If any of these apply (for example, recent license change or network changes), correct them and restart Word.
    5. If Copilot still doesn’t work
      • Follow the full steps in How to find and enable missing Copilot button in Microsoft 365 apps (account, build, and license refresh steps).
      • If the issue persists after these steps, contact Microsoft 365 support so they can verify the subscription, activation, and any account conflicts on the backend.
