Something is seriously wrong with Microsoft Outlook and other popular Microsoft services like Teams, Microsoft 365, Copilot and others, as more than 100,000 users are flocking to the popular outage-reporting website Downdetector to report issues. That number has dropped a bit since then, but it's still a very widespread outage.

For its part, Microsoft has posted on X to its Microsoft 365 Status account about the issue and what it's doing to get things back in order. I eventually got the Microsoft 365 status page to load, and it's been keeping us updated on the latest issues.

As of this post, Microsoft Outlook is sitting at more about 119,000 reports on Downdetector, which is a bit down from the peak of 130,000 but still a staggeringly large number of people having an issue with the productivity service.

While we're working to mitigate impact, we've confirmed the issue may affect Microsoft 365 service connectivity for users in any region, more information will be provided in the Microsoft 365 admin center under EX1550543.November 12, 2026

Microsoft is aware of the issue and working on it. The company took to X to update users that it's "working to mitigate impact" and has "confirmed the issue may affect Microsoft 365 service connectivity for users in any region."

It didn't provide an updated time for when everything would be back to normal, but hopefully it can get things sorted quickly so emails and calendar alerts can start going again.

While Outlook is getting the most attention in terms of raw reports, it's actually the whole of Microsoft 365 that's having problems, so other services are also experiencing outages that are impacting users, just not at the same scale as Outlook.
