Microsoft outage disrupts Outlook, Teams, and Copilot globally

Microsoft suffered a global outage affecting Outlook, Teams, and Copilot, spreading across Europe and Asia-Pacific after hitting tens of thousands of users in the United States. The disruption impacted public agencies in Australia, Japan, and the US, as well as companies like OpenAI and Anthropic. This is the second interruption of Microsoft 365 services since the start of the year, raising new questions about infrastructure reliability. Downdetector reported over 130,000 Outlook disruption reports in the US at peak, with incidents also reported Friday morning in India, Australia, and Japan. Microsoft said the issues mainly affected Microsoft 365 features dependent on Exchange Online and email services, while others remained operational. The company detected no malicious activity and noted partial improvement in some regions, though full restoration is still pending.
