How to use it
- Read the live status above. It tests Microsoft Copilot from outside your network.
- Open the official Microsoft 365 Status (work and school accounts) page for confirmed incidents.
- If Microsoft Copilot is up, work through the fixes below, cheapest first.
- Press the report button if it still fails, so other visitors see it.
Is Microsoft Copilot down for everyone or only for you?
Microsoft has several products named Copilot, and they fail differently. The Copilot app and website for personal use sign in with a personal Microsoft account. Microsoft 365 Copilot, used inside Word, Outlook and Teams at work, needs a license and runs under your organization's tenant. Windows also includes a Copilot app. A problem in one does not mean the others are down.
Our check requests the Copilot website and the Microsoft account sign-in page from outside your network. For work accounts, the Microsoft 365 status page and the admin center service health page are the official places to see incidents. Generic errors can also come from a busy backend or an overly long prompt, so a retry is a fair first step.
The live check on this page requests copilot.microsoft.com and login.live.com from our servers every few minutes. A normal answer from those addresses means the service is reachable from outside your network. It does not prove that every feature inside Microsoft Copilot works, which is why the problem reports and the fixes below matter.
What usually breaks with Microsoft Copilot
Sign-in
The Copilot app will not sign in or asks again and again. The Windows app needs a personal Microsoft account, not a work or school account.
Something went wrong
A prompt fails with a generic message. This can be a temporary backend or capacity issue, or a prompt that is too large.
Missing Copilot in Microsoft 365 apps
The Copilot button is not in Word or Outlook. This is usually a license or app update matter, not an outage.
Connectivity
Copilot cannot connect, often because a firewall, proxy or network policy blocks it.
Chats and content
Past chats or files are not visible after an app update. Microsoft notes content can take time to move into the updated app.
How to fix Microsoft Copilot when it only fails for you
Start at the top. The first steps are the cheapest and fix most cases that are not a real outage.
- Retry with a shorter prompt. Wait a minute and send a simpler, shorter message. Microsoft's own answers note that complex or very large prompts can fail.
- Run the Copilot connectivity troubleshooter. Open the Get Help app on Windows, search for Copilot and run the connectivity troubleshooter. It checks firewall rules and other blockers.
- Confirm the right account. In the Windows Copilot app sign in with a personal Microsoft account. For Microsoft 365 Copilot use your work or school account that holds the license.
- Run the license troubleshooter. For work accounts, Get Help also has a Copilot license troubleshooter. Your admin can check that a license is assigned.
- Check third-party cookies in the browser. On the web, allow cookies for the Copilot site in your browser settings and reload the page.
- Repair or reset the app. On Windows go to Settings, Apps, Installed apps, open Copilot, choose Advanced options and select Repair, then Reset if needed.
- Try another network. Switch to a phone hotspot. If Copilot works there, a firewall or proxy on your main network is blocking it.
- Check Microsoft 365 service health. Work users should open status.cloud.microsoft or ask an admin to view Service health in the Microsoft 365 admin center.
If none of this helps and the live check above shows the service as up, read our guide on why a website is not loading, or see how to flush DNS.
Common Microsoft Copilot error messages
| Message or code | What it means | What to do |
|---|---|---|
| Something went wrong | A generic failure. It may be a temporary backend problem, capacity limits or a prompt that could not be processed. | Wait, retry with a simpler prompt and check Microsoft 365 service health if you use a work account. |
| License validation errors | Microsoft has an article on license validation errors in Copilot. They relate to the Microsoft 365 Copilot license on your account. | Sign in with the licensed account and ask your admin to confirm the license assignment. |
| Cannot connect to Copilot | Copilot could not reach Microsoft's services, often due to firewall rules or other network blockers. | Run the Copilot connectivity troubleshooter in Get Help and test another network. |

Frequently asked questions
How do I check if Copilot is down?
Run the live check above. Work users should also open the Microsoft 365 status page or the admin center service health. Personal users have no dedicated Copilot status page that I could confirm.
Why does Copilot say something went wrong?
It is a generic message. Microsoft's support answers list temporary backend problems and heavy prompts among the causes. Retry before changing settings.
Why does Copilot work in the browser but not the app?
The app may be signed in with a different account or need a repair. Sign out, sign in with a personal account and reset the app.
Is Microsoft 365 Copilot the same as the free Copilot?
No. Microsoft 365 Copilot is a licensed work product. The free Copilot uses a personal Microsoft account. Their outages can differ.
Do I need to ask my admin?
For work accounts, yes, if a license or tenant policy may be involved. Admins can see service health and open a support case.
