If you have an Office 365 Home, Personal, or University subscription, you now have the option to install Office 2016 or Office 2013 on your PC. You should only install Office 2013 if you’re having specific compatibility issues with your Office 2016 upgrade. If you connect to an Exchange 2007 mailbox, you might want to stay on Office 2013 or even uninstall Office 2016 and reinstall Office 2013.
Tip: You can create and share documents between Office 2016 and Office 2013 without worrying about compatibility issues. If you create a document using an Office 2016 application and you send it to someone who’s using Office 2013, the recipient can still open and edit the document in the corresponding Office application. The same is true for documents going from Office 2013 to Office 2016.
