Office 2019 (for both Windows and Mac) is a one-time purchase and does not receive feature updates after you purchase it. Office 2019 includes a meaningful subset of features that are found in Office 365, but it's not part of Office 365. What are the feature differences between Office 2019 for Mac and Office 365 for Mac? Office 2019 is an upgrade to earlier versions of on-premises Office, including Office 2016. Office 365 is the subscription service of Office, and it will have the most creative, collaborative, intelligent, and secure features to go along with cloud connectivity.
