Offline is easiest. Online is not possible using Office 365. I haven
I like the fact that the Office applications are available with Office 2019. You can download Microsoft Office 2019 in a variety of languages, like French, Chinese, Russian/Simplified and so on. A download link is included in the software description. I do not like the “Microsoft Office 365 E3” branding, but I understand that Microsoft wants to keep you around for more Office 365 apps in the future, as they do with Office and OneDrive. My biggest annoyance with Office's naming, as noted above, is the names of different editions. At this time, I have no desire to pay for Office 2019. Even “Professional” is not appealing as it has no relationship to the Office software itself. At this time, I have no desire to pay for Office 2019, but if the Office licensing structure changes for a newer version of Office at a later time, maybe this.
