Microsoft outage: Outlook, Copilot and Teams remain disrupted, over 200,000 user issues reported

On Thursday, Microsoft experienced a widespread global outage affecting services like Outlook, Teams, and Copilot. As restoration efforts continued, numerous businesses reliant on Microsoft were also impacted. Downdetector recorded a peak of approximately 200,000 user issue reports shortly after 1pm New York time, although the number of new reports has since diminished for applications such as Outlook and Copilot.

Microsoft stated that they were making progress in restarting affected services and servers, adding that remediation actions would be expanded as stability was confirmed. Bloomberg reported that the company deployed fixes on malfunctioning systems and rerouted user traffic away from affected servers. Following an update around 6pm New York time, Microsoft noted "limited recovery in some regions."

The outage disrupted other businesses dependent on Microsoft, including OpenAI and Anthropic, with OpenAI investigating issues with Microsoft connectors and Anthropic encountering problems with the Microsoft 365 connector due to an upstream provider issue. Electric truck manufacturer Workhorse Group had to reschedule its Q3 results announcement due to the global Microsoft outage.
