Summary
About 500 Outlook issues were still reported on Downdetector at 9 a.m. ET Tuesday, even after Microsoft said mailbox connectivity had returned to expected thresholds late Monday.
Microsoft said full service was still improving by 6:30 a.m. ET and had entered extended monitoring, while some search functions remained unrestored and its status page still showed Microsoft 365 service degradation.
The outage began just before noon ET Monday and peaked at nearly 6,000 complaints around 12:24 p.m. ET; 39% of users said they were unable to receive emails.
Microsoft traced the disruption to Exchange Online functionality, saying it was reviewing telemetry and diagnostic data to isolate the source.
OpenAI also saw a separate outage Monday, with nearly 1,400 reports peaking around 1:13 p.m. ET before ChatGPT service was restored by about 4:05 p.m.
