IndiGo has issued an advisory stating that its email support services are affected by a global Microsoft outage. The airline has directed passengers requiring urgent assistance to use 6E Skai, its customer support platform.

The Microsoft outage began on November 12 and continued into November 13. According to Downdetector, nearly 130,000 reports of Outlook-related problems were recorded in the US shortly after 1 pm Eastern Time on Thursday. Microsoft attributed the issue to elevated infrastructure load and unresponsive servers.

Microsoft's public service page showed degradation in business and enterprise products on November 13. The company is checking whether repairs have taken effect and whether the machines are recovering as intended.

Microsoft has not confirmed any malicious activity causing the incident. IndiGo confirmed that all other customer-support channels remain operational, and there is no indication that booking or check-in has stopped.

The airline has linked the interruption to its email support with the global Microsoft outage but has not announced a restoration deadline for its services. The advisory does not indicate any disruption to flight operations.
