Microsoft is experiencing a global outage affecting Outlook, Teams, and Copilot for about 12 hours, impacting tens of thousands of users in the US and Asia-Pacific. The company has not yet resolved the issue. The outage peaked with roughly 130,000 reported Outlook problems in the US, according to Downdetector. Microsoft stated that affected Microsoft 365 functions depend on Exchange Online and email, with no evidence of malicious activity, attributing the issue to server problems. The disruption has hit government agencies in Australia, Japan, and the US, plus companies like OpenAI and Anthropic. Australian officials compared it to the 2024 CrowdStrike incident.
