Agile in Project is available for Project Online Professional and Project Online Premium subscriptions. The feature works with Project standalone .mpp files and with Project Online. It does not work with Project Server 2016—if you open Project connected to Project Server 2016, the agile in Project feature won’t show up. If you open an .mpp file with agile data in a previous version of Project, you won’t see the agile fields, but the agile data won’t be lost.  Contact us with any questions.
