Service Alert: Microsoft 365 Outage Affecting Outlook and Teams

Active incident

Last updated: Thursday, November 12, 2026, 3:00 PM ET. We will update this post as Microsoft reports progress.

Microsoft is investigating a widespread Microsoft 365 outage that began around noon Eastern on Thursday, November 12. Many users cannot connect to their mailboxes in Outlook and Exchange Online, on the web, desktop and mobile apps. Users have also reported problems with Teams and Copilot.

What Microsoft has said

  • The issue was first seen in the Americas. Microsoft has since said it may affect Microsoft 365 connectivity for users in any region.
  • Microsoft says part of its infrastructure is experiencing elevated load, which is likely contributing, and that it has begun redistributing connection traffic across its worldwide infrastructure to balance the load.
  • Microsoft has not given an estimated time for full restoration.
  • A separate Teams issue in North America earlier in the day was reported as recovering through Microsoft's automated systems.

This is on Microsoft's side

If Outlook or Teams isn't working for you right now, your computer, network and account are almost certainly fine. There is nothing to fix on your end.

What we recommend for now

  • Don't reset passwords or reinstall Outlook. It won't help, and it can create sign-in problems once service returns.
  • Use phone or text for anything urgent until email and Teams are stable.
  • Watch for phishing. Scammers often send fake "Microsoft outage" or "verify your account" emails during events like this. Don't click links that ask you to sign in.
  • Expect some delays after recovery. Queued email may arrive late or out of order.
  • Admins: follow the incident in the Microsoft 365 admin center under Health → Service health, incidents EX1550543 and MO1550821, or on the @MSFT365Status account.
