From the Outlook Team:

We are pleased to announce an update to Outlook.com that lets you make the most of the moments that matter to you—featuring a refined inbox, new ways to collaborate, an upgraded calendar and much more. This update is rolling out today, in Preview, to a small group of customers and is the first of many innovations coming as we upgrade Outlook.com to a new Office 365-based infrastructure. These new features will be made available to a broader audience through an opt-in program in the coming weeks.
