Microsoft shares dipped in early trading Friday as a global outage of Outlook, Teams and other Microsoft 365 services stretched into a second day. The stock fell as much as 1.8% to $513.82 shortly after the open, then pared its losses. It was near $520.75 as of 9:45 a.m. Eastern time, down about $2.25, or 0.4%, from Thursday’s close of $523.00. CNBC reported earlier that the shares were more than 1% lower in premarket trading.
The problems began early Thursday afternoon Eastern time. Users reported trouble with Outlook email, Teams, SharePoint and Copilot. Outlook drew more than 130,000 user reports on Downdetector at Thursday’s peak, according to Newsweek and NBC Chicago.
Microsoft first said part of its infrastructure was under “elevated load across multiple regions.” It later said a number of servers had become unexpectedly unavailable, straining the remaining infrastructure. In an update early Friday, its status page said: “At this time, we have no evidence of malicious activity associated with this incident.”
Around 9 a.m. Eastern time, Microsoft said email queues had significantly reduced and were approaching normal levels, CNBC reported. In a 9:10 a.m. update, Microsoft said its recovery efforts were ongoing and “may take additional time to resolve,” and that it was still working “to pinpoint the source of the issue.” The update listed Outlook.com, OneDrive, OneNote, Microsoft To Do, Teams and Microsoft 365 for the web as affected. Microsoft has not named a root cause. Its next update is due by 11:30 a.m. Eastern time.
