The latest update says:
25/01/2017 We’ve been hearing from a number of customers that they need more time to get off Project 2013 so we have decided to extend support for Project 2013 working with Project Online for 6 more months. You now have until August 31, 2017 to move to Project 2016 (Date may change – could be a little earlier – 6/30/2017).
Project Online requirements are changing
Action Required by: February 28, 2017
Details: Beginning February 28, 2017, Project Online will require the latest version of Project to connect to Office 365. We are making architectural changes to features in Project Online which impact older versions of Project, connecting to Project Online. If you are using Project 2016, you need to be on a supported build to connect to Project Online. For Project Professional 2016 customers, the RTM build (16.0.4266.1000) is the minimum build. For Office 365 customers using the Project Online Desktop Client (the subscription version of Project Professional 2016), you need to be on the previous Deferred Channel build (currently build 16.0.6741.2088) or any other build that is more recent. If you are using any prior version of Project, you will encounter issues connecting to Project Online. This change will not affect you if you are not connecting to Project Online. Make sure you’ve upgraded to a supported Project 2016 build, by February 28, 2017, to continue connecting to Project Online without interruption.
