There are major disruptions to several Microsoft services. The difficulties mainly concern Outlook and Microsoft 365, but the reports also involve other company platforms, from Teams to OneDrive, up to Copilot and Xbox.
The extent of the problem is highlighted by the data collected by Downdetector, the portal that monitors anomalies reported by users. In the United States the number of reports has increased rapidly, while similar problems have also been reported in other countries, including Italy.
Outlook Not Working: What’s Happening
Among the services most affected is: Outlook, the email system used daily by millions of people and businesses. Users report difficulties accessing email inboxes, connection errors and problems sending or receiving messages.

The accident was identified with the code EX1550543which administrators can consult in the Microsoft 365 management center.
Not just Outlook: problems have also been reported for Teams, OneDrive and Copilot
The anomalies don’t appear to be limited to email. Reports have appeared on Downdetector relating to numerous Microsoft products, including Teams, OneDrive, Copilot, Azure, Xbox and Microsoft 365.

Also complicating the picture are reports coming from the United States relating to platforms outside the Microsoft ecosystem, such as Gmail, Google, Amazon Web Services and Steam.
