Microsoft Planner is a planning application available on the Microsoft Office 365 platform. The application is available to premium, business and educational subscribers to Office 365.
On 6 June 2016 Microsoft made the application available for general release and intends to roll it out over coming weeks to eligible subscription plans.
Planner enables users and teams to create plans, assemble and assign tasks, share files, communicate and collaborate with other users, and receive progress updates via various means on the Office 365 platform. Each new plan created in Planner automatically creates a new Office 365 group.
