Why is Copilot not working . date Nov 12, 2026

The Copilot errors on November 12, 2026 were associated with a broader Microsoft service incident, not a problem isolated to your device or to Texas. Reports from the same date included Copilot failures in the Windows app and Edge, alongside disruption to Microsoft 365 services and sign-in.^1^

What to do

1. Check the public Microsoft service health status page for the current incident and recovery status.^2^
2. If this is a work or school account, ask your Microsoft 365 administrator to open: Microsoft 365 admin center → Health → Service health → Active issues Microsoft is working on.
   This provides tenant-specific impact and Microsoft’s latest restoration updates.^3^
3. Wait until the incident shows Service restored, then close and reopen Copilot and start a new conversation.

There is no need to repeat the app updates, Windows/device updates, restart, or internet checks you already completed while the incident remains active. No official status information identified Texas as the sole affected area.

If Copilot still fails after service restoration

Run the dedicated Windows connectivity check:

1. Open Start → Get Help.
2. Search for Copilot connectivity troubleshooter.
3. Run it and review the findings for firewall rules or other connection blockers.^4^

If it finds nothing and the status page shows the service as restored, submit Share your feedback from the error screen. Include the approximate failure time, whether you used the Windows app or Edge, your account type (personal versus work/school), and a screenshot without personal information.
