Office 2016 is the recommended version of Office 365 ProPlus and includes all the latest upgrades and new features. As we announced in September 2015, when we released Office 2016, beginning March 1, 2017, the Office 2013 version of Office 365 ProPlus will no longer be available for installation from the Office 365 portal.
How does this affect me?
Beginning March 1, 2017, your users will no longer see Office 2013 as an option for download through the Office 365 portal, and admins will no longer have the option under Software download settings in the admin portal to choose to enable Office 2013. In addition, we will no longer provide feature updates for this version, nor provide support.
What do I need to do to prepare for this change?
We recommend you install Office 2016 as soon as possible to have the latest and greatest features and support.
