Is Microsoft down? Thousands report Outlook 365 systems not working - latest updates

Thousands of Microsoft users have reported problems with their Outlook 365 email systems.

Just under 16,000 users were reporting problems as of 3.30 p.m. ET Thursday, according to tracking site DownDetector.com. And there seems to still be issued this morning.

The outage has lasted for over eight hours with no clear sign of abating. At one point a Microsoft message indicated that an intended mitigation caused problems elsewhere in its infrastructure.

Reports on DownDetector seemed to be dropping, but have now spiked again. There are 1000s of reports quickly appearing on the outage-tracking site Down Detector. Microsoft 365 has received more than double the number of initial reports.

On the official status page, Microsoft updated with a current status that now reads: “We’ve identified elevated service load combined with temporary capacity constraints during maintenance resulted in impact. We’re seeing positive signs of recovery in mail delivery, and mitigation actions are in place to better manage service load. While some connectivity impact remains between Microsoft Defender for Office, Microsoft Purview, and Exchange Online, and DNS lookup failures, engineers are actively working to restore full functionality."

Microsoft 365 said on X: 'We’re seeing continued improvements in service availability and functionality as a result of our load-balancing efforts. We’re actively monitoring performance and making targeted adjustments to further improve stability and availability, while continuing recovery actions to ensure a reliable service experience”
