Microsoft said most Outlook and Teams services have been restored as of Monday evening, after a day of technical delays.
The company added that full restoration of services would take place on Tuesday. At the height of the outage, tracking site Downdetector showed more than 5,000 user-reported issues, although this data does not fully reflect the scale.
“We have restored functionality to all affected services except Outlook on the web, which is still affecting a small number of users,” Microsoft wrote in a post on to make a full recovery.”
On Monday afternoon, the company said it had seen some recovery after implementing a fix for the problem, and that outage reports on Downdetector had dropped sharply. At around 7:30 PM ET, the tech giant estimated that the issue would be resolved within three hours.
By midday, the company said the fix had reached “approximately 98% of affected environments,” although reports of Downdetector continued to increase. It may take some time for updates to make their way to customer systems.
However, Microsoft subsequently noted that these restarts were “slower than expected for the majority of affected users” and did not yet provide an estimated time for a resolution. At 2:00 PM ET, the company said it was still experiencing recovery delays.
The outage has inconvenienced many office workers, although some US users on X celebrated the small break ahead of the Thanksgiving holiday weekend.
Technical glitches have had serious consequences around the world this year, although Microsoft’s case is not as widespread in comparison. In what has been called the largest IT failure in history, CrowdStrike’s software glitch over the summer halted air travel, disrupted hospitals and cost Fortune 500 companies more than $5 billion in direct losses.
