Microsoft platforms remain unstable and users are experiencing access difficulties. In addition to Outlook, services such as Microsoft 365, Teams, Microsoft Store, Copilot, OneDrive, Azure, and the Microsoft Account tool have been reporting outages since the afternoon of Thursday, November 12, 2026.
The company stated that it has suspended all updates, begun redirecting traffic away from the affected infrastructure, and initiated a reboot of the problematic servers. In updates released overnight and throughout this Friday, November 13, 2026, the company indicated that the measures taken have not yet managed to restore services in a stable and lasting manner. According to the company, there was a partial recovery in some regions following the initial adjustments, but the actions did not result in sustained stability.
Microsoft's preliminary investigation indicates that the infrastructure overload stems from the unexpected unavailability of a large volume of servers, rather than a general increase in data traffic. With the failure of these servers, the load was transferred to the remaining infrastructure, causing connection errors. The monitoring platform Downdetector recorded tens of thousands of notifications from users affected by the failures in the company's tools across different regions.
