Office 2021 Professional Plus vs. Microsoft 365

Microsoft Office 2021 Professional Plus provides fixed-feature desktop applications.

Microsoft 365 is subscription-based and offers ongoing application updates, additional cloud services, and collaboration features depending on the selected plan.

Office 2021 Professional Plus does not include a Microsoft 365 subscription, Exchange Online mailbox, SharePoint Online service, or additional OneDrive storage.

Microsoft Office 2021 is now outside its support lifecycle.

License & Activation Information

Retail Online is a seller-defined label and does not independently establish a Microsoft retail licensing entitlement.

Microsoft Office LTSC Professional Plus 2021 was distributed through organizational volume licensing programs.

A product key that supports multiple activations does not necessarily grant the right to install and use the software on the same number of devices.

The actual number of licensed computers, activation method, installation eligibility, and transfer rights depend on the license agreement supplied with the product.

Customers should verify the license source and five-device entitlement before purchasing.
