New York (CNN) –Microsoft said most Outlook and Teams services were restored Monday evening after a day full of technical delays.
The company added that full restoration of services will take place on Tuesday. At the height of the outage, monitoring site Downdetector recorded more than 5,000 problems reported by users, although this data does not fully reflect the scale of the problem.
“We have restored functionality for all affected services except for Outlook on the web, which is still experiencing issues for a small number of users,” Microsoft wrote in a post on X shortly before 11 p.m. ET. “We are monitoring and addressing this issue to ensure a full recovery.”
As of Monday afternoon, the company said it had seen some recovery since fixing the issue, and the number of crash reports on Downdetector had dropped sharply. Around 7:30 pm ET, the tech giant estimated the issue would be resolved within three hours.
By midday, Microsoft said the fix had reached “approximately 98% of affected environments,” although the number of reports about Downdetector continued to grow. It may take some time for updates to be reflected on users’ systems.
However, the company later noted that these reboots were “slower than expected for most affected users” and still did not provide an estimated time to resolve the issue. At 2:00 pm ET, the company said it continued to face delays in recovery.
The outage affected many office workers, although some US X users noted a brief pause just before the Thanksgiving weekend.
Technology glitches have had major repercussions around the world this year, although Microsoft’s case has been less widespread in comparison. Over the summer, a problem with CrowdStrike’s software grounded air travel, disrupted hospital operations and caused direct losses of more than $5 billion for Fortune 500 companies in what was called the largest IT outage in history.
