What's the difference between Microsoft 365 and Office 2021?
Office 2021 is sold as a one-time purchase, which means you pay a single, up-front cost to get Microsoft 365 apps for one computer. One-time purchases are available for both PCs and Macs. However, there are no upgrade options, which means if you plan to upgrade to the next major release, you'll have to buy it at full price.
