Thai Banks Report Email Disruptions Following Global Microsoft 365 Outage

On November 13, 2026, multiple commercial banks in Thailand issued notifications to customers regarding temporary email service disruptions. According to reports from Prachachat Business, these technical issues are linked to a significant global outage affecting Microsoft 365 services. The disruption has impacted the internal and external communication channels of several financial institutions, including Bangkok Bank, as they work to address the connectivity problems. For residents and travellers in Thailand, this outage may result in delays when attempting to contact bank support teams via email or receiving automated transaction notifications. While digital banking applications and ATM services are not explicitly reported as being down, users should exercise caution and anticipate potential communication lags during this period. It remains to be confirmed how long the restoration process will take and whether other digital banking services might experience secondary impacts as Microsoft works to resolve the global technical failure. Customers are advised to monitor official bank social media channels or mobile applications for the most current updates regarding service availability and alternative contact methods.
