The Office Online versions are not offered as a replacement for the full-featured desktop Office applications, they are only offered so users can quickly read an Office document online or make some minor changes to the application because most of the features in the desktop versions are not supported in the limited online versions. Therefore, that’s the terminology I will use in this article. The online versions of Office applications are usually referred as Office Online apps (e.g., Word Online app), while the desktop applications that you install on your workstation are called Office Desktop apps (e.g., Excel Desktop app). However, there are many differences between the two versions. Microsoft Office 365 supports both the desktop versions of Microsoft Office applications, which are installed on a workstation, and the online versions of Office applications that can be opened, viewed, and edited in a Web browser.
