Issues with Activating Copilot in Word 365 Despite Troubleshooting Steps

Hello,

I am experiencing issues with activating Copilot in Word 365. Here are the steps I have already taken:

1. License:
   • Verified that I have a current Microsoft 365 Family subscription. Copilot works fine on another computer.
2. Office Updates:
   • Ensured all Microsoft 365 apps are up to date.
3. Add-Ins:
   • Checked the Add-Ins: Copilot does not appear in the Add-Ins.
4. OneDrive:
   • Resolved issues with adding a OneDrive account by restarting OneDrive.
5. Windows Update:
   • Performed a Windows update to ensure the operating system is up to date.
6. Copilot Function:
   • Attempted to use Copilot in Word: Clicking "Chat with Copilot" does nothing.
7. Control Panel:
   • Checked Programs and Features: Both the German (de-de) and English (en-us) versions of Microsoft 365 are installed.
8. Privacy Settings:
   • Reviewed and activated relevant privacy settings in Microsoft 365.
9. Update Channel:
   • Had difficulty finding and checking the update channel.
10. Repair Office Installation:
    • Performed an online repair of the Office installation.
11. Copilot Troubleshooter:
    • Used the Copilot troubleshooter but found no solution for the specific problem.
12. Reinstall Office:
    • Uninstalled both versions (de-de and en-us) of Microsoft 365.
    • Restarted the computer.
    • Reinstalled Microsoft 365.

Despite these steps, Copilot still does not work in Word 365. Any suggestions or additional troubleshooting steps would be greatly appreciated.

Thank you!
