A massive Microsoft outage is causing headaches for businesses, government agencies, and educational institutions worldwide. Millions of users have been unable to access key services like Outlook, Teams, and Copilot for hours.
Microsoft Struggles to Manage Major Outage
Microsoft is grappling with one of the most severe IT failures in recent years. Since Thursday, numerous services from the U.S. company have been disrupted. Outlook, Teams, and the AI assistant Copilot are particularly affected. Users worldwide reported ongoing issues on Friday. At the outage portal Downdetector, around 200,000 complaints were logged at times. Although the number of new reports has since decreased, a full all-clear has not yet been issued. Typically, similar Microsoft disruptions are resolved within a few hours.
The outage hits Microsoft in a sensitive area: Its programs are part of daily life for millions and are used in businesses, schools, universities, and government agencies. In addition to the well-known Office services, other offerings under the Microsoft 365 umbrella were also affected. These include tools for file sharing, IT management, and cybersecurity.

Overloaded Servers Instead of Cyberattack?
During the outage, Microsoft released several statements on its status page. Initially, attempts to reroute traffic from the affected servers to other systems did not achieve the desired success. Investigations revealed that a central process on the servers is overloaded. As a result, the systems no longer respond, causing additional available capacities to be lost.
The company is therefore searching for the cause of the unusually high data traffic. While Microsoft does not explicitly rule out a targeted cyberattack based on current knowledge, it stated that there are no indications of malicious activities. When all services will function without disruptions again remains unclear.

From Schools to Ministries: The Impact is Enormous
The effects highlight how dependent many organizations are on Microsoft. Problems were reported in more than 70 countries. In the U.S., schools, universities, and hospitals warned of communication restrictions. The commercial vehicle manufacturer Workhorse even had to postpone the release of its financial figures.
Government agencies also felt the impact: Japan’s Ministry of Finance was unable to receive emails for most of the day. Some agencies resorted to an unusual emergency solution by posting paper notices for journalists. At the Reserve Bank of Australia, Outlook also failed in several departments, but important business operations continued. New Zealand’s immigration authority temporarily suspended the processing of all visa applications. At the fashion company PVH, which owns Calvin Klein and Tommy Hilfiger, discussions with employees about an announced job cut had to be postponed due to the technical issues.
Systems Gradually Coming Back Online
Microsoft has been able to narrow down the technical problem. Servers that went down were reconfigured, and traffic was redirected to functioning servers. This led to renewed overloads. As of now (as of Nov. 13, 2026, 8:30 a.m.), the situation is easing somewhat; Outlook & Co. are available again for many users. However, temporary outages or delayed server responses should still be expected. When all services will be fully operational again remains unknown.
