- Microsoft 365 services including Outlook and Teams were disrupted for more than five hours on Thursday.
- Eurocontrol’s Brussels headquarters asked airlines to communicate by phone while email was unavailable.
- HK Express said scheduled passenger flights continued, but asked travelers to arrive earlier for check-in and baggage drop.
SpiceJet cancelled three Delhi departures on November 13, 2026, while a Microsoft 365 outage disrupted airline email services. The flights were bound for Pune, Leh and Mumbai.
Passengers needing flight updates should contact the airline directly. IndiGo also said its email support was affected, while HK Express reported disruption to some back-office work.
Three Delhi departures were cancelled and two more delayed
Two other services, Delhi–Darbhanga and Delhi–Mumbai, were delayed. The Delhi Airport advisory said the airline was facing operational challenges affecting some flights and urged passengers to contact the carrier for updates.
An airport official said: “Flight operations at Delhi Airport have not been impacted due to the Microsoft outage”. The statement distinguished the airport’s flight operations from the difficulties reported by the airline.
The airport’s advice was practical. Check directly with the carrier about flight status and travel plans.
Airline communications and airport processes were affected in several regions
In India, IndiGo said its email support could not reliably receive customer messages, but other support channels remained available. Akasa Air reported delays in its email support. Both said their flight operations were unaffected.
Malaysia Airlines reported intermittent email problems and warned that feedback sent through its website might be affected. The carrier asked customers who submitted feedback during the disruption to send it again after service returns. CemAir in South Africa also reported system problems and directed customers to its phone line or website live chat.
In Hong Kong, Cathay Pacific warned that passengers using Microsoft-hosted email might receive automated flight notifications late. The airline said its operations continued without disruption. HK Express reported back-office difficulties but said scheduled passenger flights were unaffected; Greater Bay Airlines said its services were running to schedule.
Some airport and air-traffic communications were affected too. Manchester Airport reported problems limited to corporate systems and minor technical processes, and used an existing workaround for domestic passengers. Liverpool John Lennon Airport said: “It's not affecting us operationally and it's business as usual”.
Eurocontrol’s Brussels headquarters said it could not send or receive email and asked airlines to communicate by phone until the issue was resolved. That affected contact with the organization, which coordinates air traffic across Europe and nearby areas.
Microsoft described infrastructure strain as recovery continued
The outage began on November 12 and continued into Friday. Microsoft 365 services, including Outlook and Teams, were disrupted for more than five hours on Thursday.
Microsoft attributed the service problems to elevated infrastructure load and servers that stopped responding. Its recovery work included moving traffic across its global infrastructure and restarting affected servers.
In a Friday update, Microsoft described improvements across regions but cautioned that some users could still face intermittent access problems or delayed email delivery as recovery continued. The update said: “continued recovery progress across affected regions, with broader improvements now observed in North America and sustained improvements across much of Europe. We're also seeing encouraging recovery signals in Asia Pacific, although some users may continue to experience intermittent access issues or delayed email delivery as mitigation progresses across the remaining affected infrastructure”.
Passengers were directed to other airline channels for help
- SpiceJet: Contact the airline directly for updates on flight status and travel plans.
- IndiGo: Use 6E Skai through the airline’s website or app for urgent assistance. Other support channels remained available.
- Akasa Air: Call its 24/7 Akasa Care Centre at +91 9606 112131 or contact the airline through social media.
- Cathay Pacific and HK Express: Cathay advised passengers to update contact details and check live flight status before travelling to Hong Kong International Airport. HK Express asked passengers to arrive earlier than usual for check-in and baggage drop.
- Malaysia Airlines: Resend feedback submitted through its website during the disruption once services are restored.
Email was not the only route to assistance. Passengers with affected Delhi flights were told to contact the airline directly.
