Over the weekend, Post Finance completed a full renewal of its central banking infrastructure – an operation that had been in preparation for more than two years but caused disruptions at certain points.
The migration involved the core IT system underpinning all banking services, requiring the transfer of millions of data points and processes onto a new platform.
According to Post Luxembourg, the operation proceeded as planned, and affected services have been gradually restored since Monday. The company is asking clients to install the latest version of the Eboo app.
However, RTL has received multiple messages from Post Luxembourg clients reporting issues with the app. In response, Post Luxembourg acknowledged that despite extensive preparations, an IT migration of this size and complexity may inevitably require adjustments before all services function optimally again.
Currently, traditional bank transfers remain possible. The instant payment function, which Post Luxembourg introduced in 2025, is expected to become available again in the coming days.
During the weekend migration, bank cards were temporarily set to offline mode – a standard industry practice during maintenance or major IT operations. As a result, some clients may have reached temporary standard limits even when sufficient funds were available in their accounts. Post Luxembourg confirmed that all client bank cards are now functioning normally again.
Post Finance's contact centre is currently experiencing high call volumes from clients with questions, leading to longer waiting times at times, despite significantly reinforced teams.
Clients are encouraged to send an email to contact.finance@post.lu rather than waiting on the phone.
