Microsoft Works to Restore Outlook, Teams, Copilot After Global Outage

The duration is the real story here: an outage that outlasts Microsoft's usual few-hour recovery window points to a deeper infrastructure or dependency problem rather than routine maintenance. Because the disruption spans Outlook, Teams and Copilot simultaneously, it hits both everyday enterprise communications and the AI layer Microsoft is pushing into those same workflows, amplifying operational impact for business customers who have consolidated onto its stack. Whether the company discloses a root cause, and whether recovery holds without relapse, is the open question.
