Outlook, Microsoft 365, Teams and more down for thousands — live updates on massive outage

 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.

Here is the latest update from Microsoft's Office 365 status page:

"We've validated an alternative health check method on a subset of affected infrastructure, which allowed the servers in that subset to successfully return to service, and we're now applying this change more broadly. We're also preparing an automated recovery process to continually detect and restart unresponsive servers, to help keep them in service while this change progresses. Additionally, our review of recent changes has identified a small number of configuration updates that we're investigating as potential contributors to the issue."

The problem isn't just related to Outlook, as Teams, Copilot, Defender XDR and more Microsoft services are affected. Some users have also reported being unable to access their OneDrive storage or Office online. Microsoft is restarting its servers with a fix in place, the company says.

As of 3:50 pm ET today, Downdetector shows 59595 reports. Although this is down from the peak of over 13K reports four hours ago, it is still a significant number.

Microsoft posted another update on its status page and it seems like things are moving forward but with some issues.

"While validating the targeted change, we found that many of the affected servers have become unresponsive, which is preventing us from confirming whether the change is effective. We're restarting these servers so they can come back online with the change in place, and we're applying the same approach to additional affected portions of our infrastructure to validate the results more broadly," reads the status page.
