Kenyan banks have been forced to abandon email-based customer support temporarily and redirect customers to WhatsApp, telephone lines and call centres following a global Microsoft outage that disrupted their communication systems.
The disruption, which affected several major financial institutions on Friday, November 13, 2026, left customers relying on alternative channels to reach their banks, raising questions about the resilience of digital infrastructure within the financial sector.
Equity Bank and UBA Kenya advised customers to use telephone and WhatsApp services for enquiries, while Stanbic Bank Kenya directed clients to its Voice Branch call centre or their relationship managers. Standard Chartered Bank Kenya also notified customers through text messages that its email service was unavailable.
The Brandspur Banking News Desk reports that the disruption extended beyond conventional banking institutions to digital financial services, exposing the extent to which financial organisations depend on external technology providers for routine customer communication.
Loop, NCBA Group’s digital banking platform, reported difficulties with both its email and in-app customer support services. The platform subsequently directed customers to telephone lines and its social media accounts for assistance.
Despite the communication challenges, none of the notices issued by the banks indicated that payment services had been affected. The reported disruption centred on customer communication channels, rather than confirmed interruptions to banking transactions.
The incident has drawn attention to the risks associated with relying heavily on a single technology provider for essential business operations. For banks that increasingly serve customers through digital platforms, the temporary loss of email can complicate complaint resolution, customer enquiries and other routine interactions.
It also highlights the importance of having alternative communication systems that can remain operational when primary technology infrastructure experiences disruptions.
Microsoft’s global outage affected email and other workplace communication services across several countries, with businesses and institutions reporting difficulties accessing their usual digital tools.
For customers of the affected Kenyan banks, the immediate concern was finding alternative ways to obtain assistance while normal email services remained unavailable.
The development offers a wider lesson for financial institutions, including Nigerian banks, as they continue expanding digital banking services and depending on cloud-based technology to support daily operations.
