Some back-office operations at HK Express were disrupted by the Microsoft 365 outage, though flights at HK Express and Cathay Pacific were operating normally, Star Headline reported.

The global outage began at about 2am Hong Kong time on November 13 and affected services including Outlook and Microsoft Teams.

Cathay Pacific said customers using Microsoft services, including email accounts, might not receive the airline’s flight-notification emails. It said it was issuing electronic boarding passes through its app, SMS and email.
