A global Microsoft service outage has affected local banks, disrupting email services at DBS and UOB. Both banks have offered customers alternative ways to get in touch.

Responding to queries from Lianhe Zaobao on Friday (13 November) morning, DBS said it had issued notices through customer channels, including its mobile app and internet banking service, informing customers that Microsoft was experiencing a global service outage and that replies to their emails might be delayed.

In its notice, the bank advised customers who wanted to view transaction alerts to use DBS or POSB digibank to manage their notification preferences and opt for mobile push notifications.

Wealth management customers can also contact their relationship managers (RMs) directly for assistance.

Meanwhile, UOB said in posts on its official website and Facebook at about 10am that it was experiencing email connectivity issues.

Customers with urgent queries or awaiting time-sensitive responses can call their relationship managers directly or contact UOB's customer service hotline on 1800 222 2121 for assistance.

Both banks apologised for the inconvenience caused by the disruption and said they would provide further updates promptly.

Lianhe Zaobao has also contacted OCBC for more information.

Microsoft's Outlook email service suffered a sudden, widespread outage, leaving users around the world unable to send and receive emails normally. At about 6.40am, Downdetector recorded 195 outage reports in Singapore. Lianhe Zaobao understands that businesses across Singapore were widely affected as the working day began, with several local government ministries and agencies also affected.
