Microsoft struggles to fully resolve global 365 service outage

Engineers at Microsoft continue working to restore full functionality to Microsoft 365 services following widespread global outages affecting Outlook, Teams, and Copilot. Disruption began on Thursday evening and quickly impacted users across 74 countries, generating roughly 130,000 incident reports worldwide.

Microsoft confirmed the disruption stems from an internal technical issue where a process managing secure connections became overwhelmed, causing servers to freeze as traffic resumed. The tech giant stated there is no evidence of a cyberattack. Recovery efforts are prioritising critical public safety, emergency, and government infrastructure. Although Microsoft reported positive initial results after restarting infrastructure and reversing recent network changes, service stability remains under continuous monitoring as servers occasionally become unresponsive under renewed load.
