After more than 24 hours of widespread disruption to Outlook, Teams, Copilot, and other core Microsoft 365 services, Microsoft announced on Saturday that all systems have been fully restored. The massive technical outage affected users in over 70 countries, creating operational bottlenecks for airlines, hospitals, government offices, businesses, and individual customers. Microsoft clarified that the issue was not linked to a cyberattack or AI agents, explaining instead that it stemmed from an earlier network capacity upgrade that came to light following a recent network change. Confirming that the root problem had been fixed, the company stated that all services were back up and running. Earlier on Friday, Microsoft had apologized to customers and pointed out that the restoration process required extra time due to the immense scale of user demand. Rather than rushing the fix, engineers brought services online gradually and tested stability at every stage across regions to prevent further disruptions. The outage, which started on Thursday, heavily impacted essential infrastructure and workplaces, prompting several government departments, courts, hospitals, and transport networks to fall back on phone calls, paper records, and fax machines. Office operations in India experienced noticeable delays on Friday, while delegates at the COP31 climate summit in Turkiye also faced difficulties accessing Outlook, demonstrating the global footprint of Microsoft 365’s hundreds of millions of users.
