Microsoft says it is seeing 'positive results' in fixing the global Microsoft 365 outage that knocked Outlook, Teams, SharePoint and Copilot offline for millions. The company applied an authentication and routing patch to part of its infrastructure and said there is no sign of a cyberattack. The outage disrupted airlines including IndiGo and Akasa Air, AI companies OpenAI and Anthropic, and governments worldwide. Full restoration has no ETA yet.
