my copilot has stopped working today.

If your Copilot has stopped working, there could be several reasons for this issue. Here are some steps you can take to troubleshoot and potentially resolve the problem:

1. Check Your License: Ensure that you are assigned a license that supports Microsoft 365 Copilot. Sometimes, newly assigned licenses can take time to propagate.
2. Verify Organizational Policies: Make sure that Copilot isn't blocked by your organization's policies. Your Microsoft 365 admin can check this for you.
3. Internet Connectivity: Ensure that you have a stable internet connection, as connectivity issues can prevent Copilot from functioning correctly.
4. Recent Updates or Resets: If there has been a recent Office update or reset, it might affect your Office activation status. Check if your Office applications are activated properly.
5. Privacy Settings: Check your privacy settings to ensure that they are not blocking Copilot.

If the issue persists after trying these steps, you may want to consult your IT department or Microsoft support for further assistance.
