Microsoft resolves global Outlook and Teams outage affecting 70 countries

Microsoft apologized and resolved a global outage affecting Outlook, Teams, and Copilot for millions of users across over 70 countries, confirming it was a technical issue, not a cyberattack or AI-related failure. The disruption, which began Thursday evening, stemmed from a problem during a prior network capacity update, triggered by a recent network change. Microsoft restored services gradually to ensure stability and will provide a full post-incident report. The outage impacted public institutions, hospitals, and transport operators worldwide, with estimated economic losses near $7 billion. Microsoft may refund approximately $800 million daily in subscription fees for affected services.
