Massive Microsoft Outlook and Teams Outage: What You Need to Know (2026)

Microsoft Outlook and Teams are experiencing widespread service interruptions, with thousands of users reporting issues on Thursday. This comes just a day after a brief outage affected the same services. According to DownDetector, over 15,000 users reported problems with Microsoft 365 products at around 3 p.m. Eastern time. Specifically, 12,000 users reported issues with Microsoft Outlook, and 500 reported problems with Microsoft Teams. Microsoft Support teams are investigating the outage, attributing the issue to service infrastructure. The company acknowledged a problem with a portion of the service infrastructure in North America, which is not processing traffic as expected. Microsoft is working to restore the infrastructure to a healthy state to achieve recovery. Users can find more information on the status page or under MO1221364 if accessible. Interestingly, Microsoft resolved a brief outage on January 21, which was caused by a third-party networking issue. This recent outage, however, is still ongoing, and the company has not yet provided an estimated resolution time. This is a breaking news situation, and this article will be updated with the latest information as it becomes available.
