Microsoft email outage hits 130,000 users; Outlook still down after server overload

Microsoft's email service experienced an outage on Thursday, affecting approximately 130,000 users who reported issues with Outlook, including inability to send or open emails. The company attributed the disruption to sudden server overload, causing multiple servers to fail during automatic health checks. Teams, Copilot, and Microsoft 365 also reported issues, though most services were restored by evening, with Outlook still affected. Microsoft stated there is no evidence of hacking or cyberattack, describing it as an internal system malfunction. The company is testing a fix by isolating and restarting small server segments before gradually reintroducing traffic.
