Microsoft Apologizes for Global Outage Affecting Outlook, Teams, and Copilot

Microsoft apologized Friday for a global outage disrupting Outlook, Teams, and Copilot, confirming it was a technical issue, not a cyberattack, and reporting broad service recovery. The disruption stemmed from a problem during an earlier network capacity upgrade that surfaced after a recent network change. Microsoft said it addressed the underlying issue and restored services gradually, validating stability at each stage due to high demand. The nearly 18-hour outage affected users in at least 74 countries, including businesses, schools, and airlines, and impacted AI connectors for OpenAI and Anthropic. Microsoft pledged a full post-incident report after its review.
