Microsoft outage disrupts Outlook and Teams for millions worldwide

Microsoft is struggling to restore services after a major outage affecting Outlook, Teams, and other Microsoft 365 offerings, impacting users, companies, and governments worldwide. The company is working to identify the cause and has ruled out malicious activity. The outage, which began Thursday and continued into Friday, has disrupted email and collaboration tools for over 430 million Microsoft 365 users. Microsoft said recovery actions are showing early stabilization, but earlier fixes did not work as expected. Governments in Australia, Japan, and Singapore reported impacts, and some businesses delayed operations. The company compared the incident to the 2024 CrowdStrike outage, which was caused by a faulty update. Hong Kong businesses reported production delays, while airlines in India said flight operations were unaffected. OpenAI and Anthropic also reported connection issues with Microsoft 365 tools.
