Office 365 contains a set of world-class collaboration tools. Organizations however are struggling how to use these tools effectively to collaborate and communicate smarter. This session is about a real-world implementation of a custom Next-Gen Social Intranet Portal at a big Dutch school (ROC). How did we realize a single starting point for employees, teachers and students, where they can meet and find everything they need for their work or study? Why do we need a social intranet portal anyway? Why not use Office 365 out-of-the-box? How did we achieve user adoption? This session addresses various design choices, like using Office 365 Groups instead of SharePoint Team Sites, the role of Yammer, integrating Delve and using Umbraco CMS for managed content. The result is an intuitive, smart, and fast portal that uses modern web technologies, works great on mobile and empowers users by making it fully personizable. The portal has been implemented as a web application hosted on Microsoft Azure and uses the Microsoft Graph to communicate with the Office 365 applications.
