In a post on X late Monday night around 11 p.m. ET, the company announced that it has “restored functionality for all affected services except for Outlook on the web, which still has issues for a limited number of users.”

The company noted that it is working on resolving remaining problems with Outlook on the web and mail delivery delays.

Initially, Microsoft reported disruptions that affected Exchange Online access and features within Microsoft Teams Calendar.

Outages began on Monday morning

According to DownDetector, a service that tracks tech disruptions, users worldwide began reporting issues around 8 a.m. ET on Monday.

By just before 11 a.m. ET, thousands had reported problems, with many taking to social media to share their experiences.

This follows a series of Microsoft 365 outages that occurred in September.
