Office 365 ProPlus is Microsoft's subscription-based enterprise Office suite that is specifically designed for organizational deployment and fully supports Group Policy through Administrative Templates (ADMX files), allowing IT admins to enforce application settings across devices.

Office Professional Plus 2016 is a perpetual (one-time purchase) volume license product, not a subscription-based licensing model, so it fails the subscription requirement even though it does support Group Policy.

Office Online is a free, browser-based version of Office that runs in a web browser and cannot be managed via Group Policy since it has no locally installed components to configure.

Office Home and Business 2016 is a perpetual retail license intended for personal or small business use, not an enterprise subscription model, and it does not support Group Policy management.
