Microsoft announced that most services for Outlook and Teams were restored late Monday after a widespread outage disrupted users throughout the day. While a small number of users continue to face issues with Outlook on the web, the company promised full restoration by Tuesday.

The disruption peaked with over 5,000 complaints logged on Downdetector, though Microsoft implemented fixes that restored functionality to 98% of affected environments by midday. Progress slowed in the afternoon, but by evening, reports of issues had significantly declined.

This outage, which impacted countless office workers ahead of the Thanksgiving holiday, is the latest in a year of major tech disruptions globally. Although significant, the scale of this incident was far smaller than the summer outage of CrowdStrike’s systems, which caused billions in losses across industries.
