We are currently investigating widespread upstream service disruptions affecting Microsoft 365 components, including Outlook, Teams, OneDrive, and Copilot. Microsoft 365 cloud environments globally. Independent monitoring platforms have logged upwards of 130,000+ incident reports, pointing to widespread authentication and backend traffic routing errors.
Users may experience connectivity errors, login failures, or issues sending/receiving messages.
Microsoft engineering teams have isolated the source of the heightened system load and mitigation steps are rolling out. While external cloud dependencies are outside our direct control, our systems remain fully operational aside from upstream integration timeouts.
We will provide updates as service health stabilizes.
