A network-level disruption struck multiple Microsoft 365 services on Wednesday evening, knocking out or degrading access to Exchange Online, Microsoft Teams, and the broader Microsoft 365 suite for users across affected regions.
The incident, tracked under issue ID MO1274150, began at approximately 8:37 PM IST (3:07 PM UTC) on April 8, 2026, and prompted Microsoft’s engineering teams to launch an immediate investigation.
Microsoft confirmed the outage was caused by a network-level disruption rather than an application or configuration fault, pointing to infrastructure-layer failures as the root cause.
The company’s internal telemetry flagged the degradation shortly after onset, and customer-reported complaints began flowing in within minutes of the start time.
