Microsoft outage disrupts Outlook and Teams for users in 74 countries

A major Microsoft outage disrupted services including Outlook, Teams, and Copilot, affecting tens of thousands of users across more than 70 countries. The company reported that several servers were unexpectedly unavailable, causing widespread connection errors. Microsoft attributed the issue to increased load on infrastructure in multiple regions, which likely caused connection failures. The company's attempts to fix the problem did not work as hoped, with only limited improvement. A process responsible for secure connections was overloaded on affected servers, and Microsoft reverted a recent configuration change that coincided with the outage's start. The outage impacted users in 74 countries, including government agencies in Australia and the US House of Representatives. Microsoft stated there is no evidence of malicious activity, suggesting a faulty update similar to the 2024 CrowdStrike incident. The company's cloud services also experienced a similar major outage in late August.
