Microsoft has confirmed that its services are fully restored after a global outage affected Teams, Outlook, and Copilot. The tech giant announced early Saturday morning that efforts to address the underlying problem had been completed. Customers using these platforms should no longer experience disruptions.
The incident began on Thursday and lasted nearly 24 hours. It impacted more than 70 countries, affecting over 430 million users worldwide. The disruption halted business operations, government services, and personal communications across multiple continents.
Microsoft global outage impact on businesses
The outage reached far beyond typical office work. Institutions from the Japanese government to the Philippines Supreme Court reported issues. In North America, trains, hospitals, and courts faced significant operational challenges.
In the United Kingdom, parts of the National Health Service, schools, and police forces were affected. UK cyber minister Liz Lloyd stated that the incident had a limited impact on critical frontline services. She confirmed there was no disruption to the transport network or 999 emergency calls.
Canada experienced different challenges. The national rail network warned passengers they might not receive email updates about their trips. Hospitals across the country also reported issues with email access. In the United States, staff at the House of Representatives told Politico that the outage set back an entire day of legislative work.
International impacts were widespread. Singapore acknowledged that some government systems were impacted. In India, the outage disrupted work for many on Friday. At the COP31 climate summit in Antalya, Turkey, advisers and officials were frustrated by their inability to access Outlook.
Microsoft Teams outage causes personal delays
The downtime affected individuals as well as large organizations. Peter Pentz, a winemaker in South Africa, said his entire business was brought to a standstill. His winery relies on Microsoft systems for daily operations and export communications.
Personal milestones were also delayed. Georgia from Staffordshire in England was in the final stages of purchasing her first home. The outage prevented her solicitor from contacting other agencies in time. She noted that hundreds of other house purchases were likely affected by the same issue.
Microsoft first acknowledged the issue at 17:54 GMT on Thursday when users in the Americas could not access Exchange Online mailboxes. Engineers began working to restore services immediately. By early Friday, the company reported only a partial recovery in some regions.
Services began to recover gradually by Friday afternoon. Microsoft stated that it restored services slowly to ensure stability once they were back online. The company apologized for the disruption, attributing the cause to a network capacity upgrade rather than a cyber-attack or artificial intelligence error.
Experts described the event as a stark reminder of the heavy reliance businesses have on a small group of big tech providers. Rob Demain, chief executive of cybersecurity firm e2e-assure, highlighted the vulnerability created by this dependence. Matt Saunders, field chief technology officer at Adaptavist, noted that while classic IT disaster planning suggests using second services for resilience, it is almost impossible for businesses to function without Microsoft tools.
Microsoft plans to release a full post-incident report once its review is complete. The company emphasized that it takes the trust placed in its services extremely seriously. The incident underscores the critical role cloud-based services play in modern global infrastructure.
