Update, 2:40 PM EST: Microsoft says a large number of its servers unexpectedly went offline, overloading the rest of its systems. It has paused all changes while it finds the cause and brings those servers back online. Besides Outlook email and Teams, SharePoint, Copilot, and Microsoft Defender may also be affected. Microsoft hasn’t said when service will be restored.
Original post, 2:00 PM EST:
Microsoft 365 is having a widespread outage today, Thursday, November 12. Starting around noon Eastern, people began reporting that they couldn’t open Outlook email, join Teams calls, or reach other Microsoft 365 services. Outage trackers logged more than 130,000 reports in the first hour and a half.
Microsoft has confirmed the problem and is working on a fix. Most reports are coming from North America, and Microsoft says users in other regions may also have trouble connecting. The problem is on Microsoft’s side, not with your computers, your network, or your accounts.
Until service is restored:
- Don’t reset passwords or reinstall Office. It won’t fix the outage and can cause sign-in problems later.
- Use phone or text for anything urgent, and let customers know email replies may be delayed.
- Watch for fake “Microsoft” emails. Scammers use outages to send messages asking you to sign in again or verify your account. Don’t click them.
Microsoft posts official updates on its Microsoft 365 service status page and on the Microsoft 365 Status account on X. If you manage your company’s Microsoft 365, the details are in the admin center under Service health.
The outage may also affect Kishmish’s ability to receive and respond to service tickets sent by email. For anything urgent, please call us.
