In this project spanning four years, attoma is supporting the teams at Orange by proposing improvements to the professional inbox tool, while training the internal teams to adopt new collaboration and production processes.


Used by more than 1.5 million professionals, the new inbox app must make it possible for professionals to have access to their emails, contacts, calendar, faxes, and text messages at any time and on all devices.

The objective for Orange is to redesign this tool while driving the evolution of work methods for its marketing, development, and design teams.


In close collaboration with Orange’s xdlab B2B team, attoma put in place agile work methods to continuously improve the inbox tool through a series of regular, recurring meetings. Every month, attoma co-designs new user journeys with the internal teams, which are then used to guide the evolution of the app’s features.

Attoma established a series of sprints punctuated by different kinds of weekly “ceremonies,” acclimating Orange’s teams to a steady rhythm of regular releases.


Attoma thus redefined the functional scope of the app, reassessed the information architecture, and proposed a user experience adapted to the use cases of each terminal. The look and feel of the interface was also redesigned, taking into account the users’ needs.

In parallel, attoma helped Orange to pool their various internal expertises, facilitate exchanges between the different services, and guarantee tangible and quick benefits for their users.
