Microsoft is racing to restore its services following a major global outage that disrupted access to Outlook, Microsoft Teams, Copilot and several other Microsoft 365 applications, affecting businesses, government agencies and millions of users across multiple regions. The disruption began on Thursday, November 12, and continued into Friday, November 13, with the company reporting early signs of stabilisation but no complete recovery. Reuters reported that the outage had lasted more than 12 hours, making it one of Microsoft’s most significant service disruptions in recent years. The incident affected organisations across North America, Europe, Asia and Australia, forcing some businesses and public institutions to rely on alternative communication channels.
Microsoft initially attributed the disruption to elevated infrastructure loads before identifying that several servers had unexpectedly become unavailable, placing additional pressure on the remaining systems. The company also identified an overwhelmed core process on affected servers as a factor contributing to the loss of capacity. Its recovery measures include restarting affected infrastructure, redistributing traffic across alternative pathways, applying technical fixes and gradually returning servers to service. Microsoft said it had observed positive results from its interventions and was working towards a sustained recovery. The company also stated that it had no indication the outage was caused by malicious activity or a cyberattack. According to Channel NewsAsia, however, service capacity remained below normal levels, with users continuing to experience intermittent access problems.
The disruption has exposed the dependence of businesses and public institutions on Microsoft’s cloud-based productivity and communication infrastructure. CX Today reported that the outage affected government agencies in Australia, Japan and the United States, while companies in the financial, shipping and aviation sectors experienced communication delays and operational interruptions. In the United Kingdom, public services, healthcare organisations, schools and police departments also reported difficulties with some digital systems. Although certain Microsoft services and features remained functional, the incident demonstrated how failures within a shared technology infrastructure can spread across multiple industries and markets. Microsoft is continuing its restoration efforts and has indicated that it will provide further technical details through a post-incident report once the situation is resolved.
