Office 365 ProPlus
Office 365 ProPlus is the always up-to-date suite of desktop apps you already know (including Word, PowerPoint, Excel, Outlook, and Teams) available as a subscription. ProPlus includes exclusive intelligent capabilities like Ideas in Excel and Researcher in Word, real-time collaboration, and advanced security features. As a user-based license, you can deploy Office on up to 5 PCs or Macs, 5 tablets, and 5 smartphones. And with 1 TB of cloud storage, you can access – and collaborate on – your files from anywhere.
Office 365 is a subscription that comes with premium apps like Word, Excel, PowerPoint, Outlook, Teams, Publisher, and Access (Publisher and Access available on PC only). The apps can be installed on multiple devices, including PCs, Macs, iPads, iPhones, Android tablets, and Android phones. Office 365 also comes with services like 1TB of OneDrive storage, and Microsoft chat and phone support. ProPlus includes exclusive intelligent capabilities like Ideas in Excel and Researcher in Word, real-time collaboration, and advanced security features. With a subscription, you get the latest versions of the apps and automatically receive updates when they happen.
Office 2019 is a one-time purchase that comes with classic apps like Word, Excel, and PowerPoint for PC or Mac, and does not include any of the services that come with an Office 365 subscription. One-time purchases don’t have an upgrade option, which means if you plan to upgrade to the next major release, you'll have to buy it at full price.

A persistent Internet connection is not required; Office 365 ProPlus runs locally on your PC. Internet access is required to install and activate Office, but IT administrators in traditional private cloud environments can deploy Office and Office updates using software distribution tools and infrastructure.
Some advanced features require internet connection (e.g., Ideas in Excel, Researcher in Word.) Connecting to the Internet regularly ensures that you can receive automatic updates and that your Office apps are on the latest versions. Internet access will also be needed to manage your Office 365 account, e.g., to change payment options or to access documents stored on OneDrive.
