Microsoft Outlook outage hits 10 hours as global users face email disruptions

Microsoft's Outlook and other Microsoft 365 services are experiencing a widespread outage lasting over ten hours, with restoration efforts not progressing as expected, leaving millions of users unable to access email. The company attributes the issue to increased load and infrastructure problems, ruling out malicious activity or cyberattacks. The outage has affected users globally, including Japanese government services and businesses in China, with reports of problems also impacting Teams and the Copilot AI assistant. Microsoft is testing alternative workflows to increase capacity, while OpenAI and Anthropic have reported connectivity issues related to the Microsoft 365 disruption. Microsoft previously faced a similar Azure cloud outage last month, and the company continues to monitor the situation as users report ongoing problems despite claims of successful restoration in North America.
