Bangkok Bank Reports Temporary Email Outage Due to Global Microsoft 365 Issues
Bangkok Bank has announced a temporary disruption to its email services caused by a global Microsoft 365 outage, advising customers to use alternative contact channels.
On November 13, 2026, Bangkok Bank issued an official notice informing customers that its email communication system is currently experiencing a temporary outage. According to the bank, this disruption is linked to a widespread technical failure affecting Microsoft 365 services globally. As a result, the bank's standard email correspondence channels are currently unavailable for both internal and external communications.
For residents and travellers who may need to reach the bank for urgent matters, Bangkok Bank has advised customers to contact their relationship managers directly at any bank branch nationwide. Alternatively, customers can reach the bank's call center by dialing 1333 for assistance.
This incident highlights the reliance of major financial institutions on global cloud infrastructure and the potential for widespread service disruptions when such platforms encounter technical difficulties. While the bank has provided immediate alternative contact methods, it remains to be confirmed how long the Microsoft 365 outage will persist and when full email functionality will be restored. Customers are encouraged to monitor official bank channels for further updates regarding the status of their digital services. The bank has not reported any impact on core banking or transaction processing systems at this time.
