Microsoft said a major Outlook and Teams outage would be resolved Monday night after facing a day full of technical delays.
At the outage’s peak, tracking site Downdetector showed more than 5,000 user-reported problems, though this data doesn’t fully reflect the scale.
By Monday afternoon, the company said it had seen some recovery after it deployed a fix to the problem, and reports of outages on Downdetector had dropped sharply. Around 7:30 p.m. ET, the tech giant estimated the issue would be resolved in three hours.
“We’ve started to deploy a fix which is currently progressing through the affected environment. While this progresses, we’re beginning manual restarts on a subset of machines that are in an unhealthy state,” Microsoft said on X earlier in the day.
Around noon, the company said the fix had reached “approximately 98% of the affected environments,” though reports on Downdetector kept increasing. It can take time for updates to work their way to customers’ systems.
However, Microsoft then noted those restarts were “progressing slower than anticipated for the majority of affected users” and did not yet provide an estimated time for a fix. At 2 p.m. ET, the company said it was still facing delays in its recovery.
The outage has hindered many office workers — though some US users on X celebrated the small break ahead of the Thanksgiving holiday weekend.
Tech outages have had dire effects around the world this year, though Microsoft’s case isn’t as widespread in comparison. In what’s been called the largest IT outage in history, CrowdStrike’s software issue over the summer halted air travel, disrupted hospitals and cost Fortune 500 companies more than $5 billion in direct losses.
