The outage, first widely reported early Thursday, was one of Microsoft’s longest and its second major service disruption this year.

Microsoft said server issues were behind the incident that also affected its Copilot AI assistant and that a broader roll-out of software fixes was stabilizing the system. It said it was not aware of any malicious activity and ruled out AI as the cause.
Outlook and Teams are two of the most widely used workplace applications with hundreds of millions of users. The outage prevented people from performing essential functions such as sending emails, managing calendars and hosting virtual meetings.
