Hi Byron Martinez,
If the Microsoft 365 Copilot app on your PC isn’t working, it’s typically related to account validation, app state, or connectivity conditions rather than a permanent issue. Copilot relies on your signed-in account, licensing, and app components to be fully synchronized before it can function properly.
Here are some quick checking steps that you can try:
1, Check account and subscription
- Confirm you are signed in with the correct Microsoft account
- Verify your subscription includes Copilot (if applicable)
2, Test if the issue is app-specific
- Open Copilot web in a browser (e.g., Edge)
- If it works there, the issue is likely isolated to the app session
3, Check connection
- Ensure stable internet access
- Temporarily disable VPN or proxy (if used)
I understand how inconvenient this can be, especially when you rely on Copilot for daily tasks. The steps above usually resolve most cases, and they also help narrow down whether the issue is related to the app, account, or environment.
