Apologising to customers and partners for the disruption, the company ruled out the possibility of a cyberattack. Microsoft Executive Vice President for Copilot, Agent and Platform Charles Lamanna said the company was reviewing the incident and working to prevent similar disruptions in the future.

Providing an update on Friday’s outage affecting Outlook, Teams and other Microsoft 365 services, Lamanna said recovery was progressing encouragingly, with service availability and email delivery performance improving across an increasing portion of the affected infrastructure.
