A widespread outage of Microsoft 365 services affected thousands of users worldwide on the evening of Wednesday, October 8, 2025, temporarily rendering key platforms such as Microsoft Teams, Exchange Online, and the Microsoft 365 admin portal inaccessible.
The outage, reported starting late in the day, impacted the ability of numerous organizations to use critical communication and business management tools. Microsoft quickly confirmed the anomaly , launching a high-priority investigation to identify the cause of the problem and restore full system functionality.
Around 10:56 PM (GMT+5:30), the company identified a possible anomaly in directory operations within a section of its infrastructure.
The error, related to the handling of user authentication and service requests, caused a back-end malfunction. Engineers then analyzed the diagnostic data to develop a mitigation strategy that would not further compromise the operational environment.
At 11:36 PM (GMT+5:30), Microsoft announced that it had begun rebalancing service loads, redirecting traffic from faulty components to functioning systems. This measure represented a crucial step toward stabilizing the platform and gradually resuming operations for affected users.
In the early hours of this morning, October 9, 2025, the company saw positive signs: traffic rerouting led to a gradual restoration of core services. Despite the improvement, Microsoft announced that its technical teams will continue to monitor the infrastructure to ensure long-term stability and prevent further outages.
The company also maintained a constant stream of updates to inform users about the progress of the rollout, confirming that most features were gradually returning to normal.
