Microsoft 365 Outage Causes Widespread Disruption, Affecting Airline Operations
A significant Microsoft 365 outage on November 13, 2026, led to widespread disruptions, impacting airline email services and causing flight cancellations and delays. The outage, which affected Microsoft 365 services like Outlook and Teams for over five hours, highlighted the critical reliance of modern businesses, particularly in the aviation sector, on cloud-based productivity suites. This event underscores the potential vulnerabilities in digital infrastructure and the cascading effects that a single system failure can have across multiple industries.
Airline Email and Back-Office Systems Hampered
The disruption to Microsoft 365 services had a direct impact on airline communications. SpiceJet, an Indian airline, was forced to cancel three flights departing from Delhi and delay two others due to issues with their email systems. These cancellations included flights bound for Pune, Leh, and Mumbai, with other services to Darbhanga and Mumbai also experiencing delays. Passengers were advised to contact the airline directly for the most up-to-date information on their travel plans.
Other airlines also reported difficulties. IndiGo, another Indian carrier, stated that its email support was affected, though other communication channels remained operational. Akasa Air also noted delays in its email support services. In Malaysia, Malaysia Airlines experienced intermittent email problems, warning that feedback submitted through their website might not have been received. CemAir in South Africa directed customers to its phone line or website live chat due to system issues.
Air Traffic Control and Airport Operations Feel the Impact
Beyond individual airlines, the outage affected broader aviation communications. Eurocontrol’s Brussels headquarters, which coordinates air traffic across Europe, reported an inability to send or receive emails. This necessitated a shift to phone-based communication with airlines to maintain operational coordination. While airport flight operations at Delhi Airport were not directly impacted, the airline’s operational challenges were a significant concern for travelers.
In Hong Kong, Cathay Pacific alerted passengers that automated flight notifications sent via Microsoft-hosted email might be delayed. HK Express reported disruptions to some back-office functions, although scheduled passenger flights continued to operate. Greater Bay Airlines confirmed that its services were running as scheduled. Manchester Airport noted that the outage was limited to corporate systems and minor technical processes, with existing workarounds in place. Liverpool John Lennon Airport stated that operations were unaffected and it was business as usual.
Microsoft’s Response and Recovery Efforts
Microsoft attributed the widespread service problems to elevated infrastructure load and unresponsive servers. The company initiated recovery efforts, which involved rerouting traffic across its global infrastructure and restarting affected servers. In an update, Microsoft indicated progress in recovery across various regions, including North America and Europe, while acknowledging that some users might still experience intermittent access issues or delayed email delivery as mitigation efforts continued across the remaining affected infrastructure.
Passenger Guidance Amidst Disruption
During the outage, passengers were directed to alternative communication channels for assistance. SpiceJet advised customers to contact the airline directly for flight updates. IndiGo recommended using its 6E Skai service via its website or app for urgent help. Akasa Air provided a 24/7 contact number and social media channels for support. Malaysia Airlines asked customers to resubmit any website feedback submitted during the disruption once services were restored. Cathay Pacific and HK Express encouraged passengers to check live flight status and, in HK Express’s case, arrive earlier for check-in and baggage drop.
