Microsoft 365 outage: 13 November 2026

Microsoft is having a global outage, and you may have trouble using some Microsoft 365 services, including Outlook and email, Teams, SharePoint, OneDrive and Copilot. You might be unable to connect at all, or things might be slow or only work some of the time. This is Microsoft’s problem, not yours. Your devices, accounts and data aren’t the cause, and you don’t need to do anything.

Updates

Fri 13 Nov 2026, 11:00 AM AEDT · Monitoring

Microsoft’s latest update (9:58 AM AEDT) says it has started returning some affected servers to service, and they’re stable so far. It has moved traffic to alternative paths where it can, with limited recovery in some regions, and is applying traffic management to reduce load. You may see a gradual recovery as your apps reconnect. Microsoft hasn’t said when everything will be back to normal. Its next update is due by 11:30 AM AEDT, and we’ll keep this page updated.

We let our clients know about the outage by email. Microsoft says some of its servers went offline unexpectedly and put too much load on the rest. It’s restarting servers, redirecting traffic and rolling out a fix.

Microsoft reports that users may be unable to connect to their mailboxes in Exchange Online, including Outlook on the web, desktop Outlook and phone mail apps (EX1550543). From 5:26 AM AEDT, Microsoft also reported that users may be unable to connect to multiple Microsoft 365 services (MO1550821).

What you can do

  • Please don’t keep resetting your password or reinstalling Outlook. It won’t help and can cause extra problems once the service is back.

  • Emails may arrive late, but they should come through once Microsoft fixes the problem. If something is urgent, call the person instead.

  • If an email you sent doesn’t go out, or you can’t find an expected email after the service is back, let us know and we’ll look into it.
