Microsoft outage disrupts Outlook and Teams for second day, cause still unclear

Microsoft is working to identify the cause of a global outage disrupting Outlook, Teams, and other services for a second day, with no malicious activity detected. The company is investigating a traffic influx and recovering backend servers. The service health page showed "service degradation" for business, enterprise, and consumer customers as of Friday morning India time. Microsoft is reverting a recent network configuration change correlated with the problem's start, though this is not confirmed as the root cause. Affected features include email access, delayed delivery, and Copilot Chat failures, while Teams core functions work. Indian users reported issues starting Thursday night, with reports spiking again Friday morning. Airline IndiGo said its email support was affected. Microsoft will publish a post-incident report once the issue is mitigated, with updates available on the Microsoft 365 admin center.
