how to fix copilot

Check Microsoft service health before changing your device because a broader disruption affecting Copilot and other Microsoft 365 services was reported on November 13, 2026.^1^

1. Check for an active incident

• Personal account: Check the Microsoft 365 Service health status and retry after any reported incident is resolved.
• Work or school account: Ask your Microsoft 365 administrator to check Health → Service health in the Microsoft 365 admin center.
• If no incident is active, continue below. Since only your account is affected, session or account state should be isolated before repairing the app.

2. Test a clean browser session

1. Open an InPrivate/Incognito window.
2. Go to copilot.microsoft.com.
3. Sign in using the same account and test a new prompt.
4. If you have multiple accounts, ensure you use the same sign-in method as previously—Microsoft account, Continue with Google, or Continue with Apple. Personal and work/school accounts remain separate.^2^

If Copilot works privately, remove only its stored site data rather than clearing every website:

1. In Edge, open Settings → Privacy, search, and services → Cookies → See all cookies and site data.
2. Search for Copilot and delete the matching entries.
3. Close and reopen Edge, then sign in again.^3^

Also temporarily disable browser extensions that block scripts, cookies, or advertisements.

3. Compare another client and account

• Test the same account in the other client: if you normally use the app, try the website; if you normally use the website, try the app.
• If available, test a different Microsoft account in a private window.

If another account works while yours consistently fails, the issue is likely account-specific, not conclusively a device problem.

4. Update and repair the Windows app

First update Windows, Edge, Microsoft Store apps, and Microsoft Copilot. Then:

1. Open Settings → Apps → Installed apps.
2. Find Microsoft Copilot, select … → Advanced options.
3. Select Repair and test Copilot.
4. If Repair fails, select Reset.

Reset can remove the app’s locally stored data and sign-in state. Windows documents Repair as the non-destructive first option and Reset as the next step.^4^

If neither works, uninstall Microsoft Copilot from Installed apps, reinstall it from Microsoft Store, and sign in again.

5. Test connectivity

Disable any VPN or proxy temporarily and try another network, such as a mobile hotspot. On Windows, run Microsoft’s dedicated diagnostic:

1. Open Get Help.
2. Search for Copilot connectivity troubleshooter.
3. Run it and review its findings.

The diagnostic checks firewall rules and other connection blockers.^5^

6. Escalate an account-specific failure

• Personal account: In Copilot, select … → Send feedback → Report a problem. Include when it started, the device and operating system, and a screenshot without personal information.^2^
• Work or school account: Ask the administrator to confirm that the Copilot license and associated service plan are assigned. If the admin center and diagnostic disagree, the documented correction is to disable the affected service plan, save, re-enable it, save again, and rerun the diagnostic.^6^
