Email service is at the core of a collaborative suite. And, good news, FOSS solutions for all collaborative uses have an unprecedented maturity. But Europe still faces a critical dependence on Office 365, with strategic and financial costs that are now undeniable.

The challenge is no longer functional, FOSS solutions suffer from an architectural limitation : a simple SSO does not create a platform. To offer a true Smart Platform Experience around the mail, we must go beyond silos solutions and build deep, consistent, cross-functional integration between independent services.

Based on the integration of DINUM's LaSuite into Twake.AI, we will analyze what is missing to offer a “Smart Platform Experience”: a standardized cross-functional layer that brings together independent services.

Samuel Paccoud, director of lasuite.numerique.gouv.fr, will comment this integration and the perspectives he identifies.

We will see how such a standard can enable a modular ecosystem, where each application remains independent but can interoperate deeply, forming a credible and sustainable sovereign workplace. This is the mission of the Open Buro consortium: to create an open foundation where architecture becomes a political act.
