Possible Microsoft 365 Outage or Service Interruption

We have had a number of clients report issues with Microsoft 365, specifically email. Downdetector is reporting a spike in user reported issues at 12:25pm ET and the Microsoft Admin center page for reports simply reports “Too many requests”. The Microsoft X / Twitter account confirms that they are currently investigating.

Updates

• Thursday, 11 November
  • 11:13am ET – Microsoft posted to their X / Twitter account, announcing the problem.
  • appx 12:05pm ET – Multiple users reported issues accessing multiple assets in the Microsoft 365 Environment
  • 3:47pm ET – Microsoft posted the following to their Status Page (working now)
    • 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.
  • 5:18pm ET – At this time, most services are still down or marginal at best
