Outlook Outage: Microsoft 365, Outlook and Teams Went Down for Thousands of U.S. Users Thursday Afternoon
Outage reports surged past 130,000 for Outlook alone by 1:27 p.m. ET, according to Downdetector figures carried by Reuters. Microsoft said it was investigating problems reaching Exchange Online mailboxes in the Americas. No cause and no restoration time had been announced as this story was filed.
Microsoft's email and workplace tools stumbled across the United States on Thursday afternoon, as Outlook, Microsoft 365 and Teams went down for thousands of users, Reuters reported, citing outage tracker Downdetector.
The reports climbed steeply around midday Eastern time. USA TODAY counted more than 22,000 Microsoft 365 reports by 12:55 p.m. ET and Outlook reports just shy of 83,000 just before 1 p.m. ET. Reuters put Outlook issue reports at more than 130,000 at 1:27 p.m. ET, alongside more than 46,000 reports for Microsoft 365 and about 3,000 for Teams.
It was the company's second disruption of the day. Microsoft posted at 10:40 a.m. ET that it was addressing Teams issues in North America and said around noon that those were resolved; just before 1 p.m. ET, it said it was investigating issues accessing Exchange Online mailboxes through multiple connection methods in the Americas. Reuters reported Microsoft also said the issue may affect Microsoft 365 connectivity in other regions.
No cause and no restoration time had been announced as this story was filed, and Microsoft did not immediately respond to USA TODAY. The story is developing; the desk will update this file when Microsoft states the services are restored.
