If you want to get it now and not wait until February, then you need to be part of the First Release program.
For Office 2016 as well as Project 2016, this release will be on the Standard Release in February 2016 and users will start to get notifications to install it at that point. This gives you extra time to prepare your support staff and users for upcoming changes. Standard Release is the default option where you and your users receive the latest feature updates when they’re distributed broadly to all Office 365 customers this occurs three times a year.
If you have Office Pro Plus from an enterprise Office 365 plan, then you have two available services branches: Standard Release (or Current Branch for Business) and First Release (or First Release for Current Branch for Business).
If you’re not using Office 365 Home and Personal subscriptions, then you’re on a branch called Current Branch, which receives monthly feature and security updates. Next, you need to know what service branch you’re on. If this isn’t selected, you will need to install the product using the “software deployment method,” which I describe shortly. You then go to Service Settings | User software and validate that Project is checked. This is accessed from the Office 365 Portal. The first setting you should have your global administrator for Office 365 check is whether Project is turned on to be managed through Office 365. The process might be slightly different based on your tenant global administrator settings for deploying software to your organization, but this article should cover all scenarios. This article outlines the steps to follow in order to upgrade your Project Pro for Office 365 from the 2013 version (15.0) to the 2016 version (16.0).
Several of our clients have had some confusion on how to obtain the latest version of Project with their existing deployment of Project Online. By default, Office updates are also downloaded and installed so the product is always up to date. It also gives you the added benefit of allowing installation of the software on up to five devices. The application runs as a click-to-run application, which means it can easily be installed from any Windows-based machine with Internet access. You can also use Project Pro for Office 365 as a standalone desktop application, as well as to connect to an on-premises installation of Project Server 2013 or the upcoming Project Server 2016.
It’s paid as a monthly service and can also be combined with a Project Online license to give you full capabilities of the online project and portfolio management (PPM) solution.
