Background & analysis
On Thursday Eastern Time, a large-scale outage hit Microsoft 365 and several Microsoft cloud services, and it lasted for hours before extending beyond 10 hours, affecting at least tens of thousands of users. The services disrupted included Outlook, Exchange Online, Microsoft Teams, SharePoint, OneDrive, and Microsoft's AI assistant Copilot. The impact was concentrated in the Americas, though fault reports also came from other regions, including Asia.
According to user reports, some people could not send or receive email during the disruption, while others ran into mailboxes that would not load or cloud files that could not be accessed. Downdetector, an outage tracking site, recorded Outlook complaint reports peaking at 138058 around 1 p.m. Eastern Time. As repair work advanced, the number of related error reports fell to roughly 34490 by the evening in Eastern Time.
The outage also affected the AI companies OpenAI and Anthropic, and it touched the work of multiple government departments in Japan and Singapore. Some civil servants reported that work email could not be sent or received properly. Reporting on the event does not state when service was fully restored, so the recovery effort is presented as still under way at the latest available point.
