Microsoft outage hits Outlook and Copilot, services recovering

Microsoft services are experiencing widespread outages, with the company reporting high infrastructure load across multiple regions causing connectivity errors. The issues are affecting Outlook, Copilot AI, and security tools like Defender XDR, though Microsoft says problems are gradually being resolved. Over 130,000 outage reports were logged for Outlook alone, with approximately 50,000 additional notifications for the Microsoft 365 suite, according to Downdetector. Third-party integrations with OpenAI and Anthropic were also impacted, while the hashtag #MicrosoftOutlookDown trended on X. Earlier the same day, the US cybersecurity agency CISA issued an alert about an unknown vulnerability in Microsoft Outlook, which the company reportedly fixed on November 10. Italy is among the affected regions, with email services gradually returning to normal.
