Global Microsoft 365 outage disrupts Teams and Exchange services – Computerworld

Manish Rawat, analyst, TechInsights, said industry estimates suggest that IT downtime can cost mid- to large-sized enterprises between $100,000 and $500,000 per hour, depending on their sector and the criticality of operations. “For large organizations, even a brief 2–3 hour outage could result in millions in lost productivity, reputational harm, and serious operational setbacks, especially in high-stakes sectors like finance, healthcare, and manufacturing,” he said.

Given the recent incidents involving Microsoft 365 services alone, experts believe that enterprises must reduce their overdependence on Microsoft 365. “Organizations should adopt robust contingency plans that include alternative communication tools, offline access to critical documents, and a comprehensive incident response framework,” said Prabhu Ram, VP for industry research group at CMR.
