Get started with Windows 365 Business

joergackermann Shared computer activation applies not only to RDS machines, it applies to things like workstations used by multiple people as well. The license refers to a 'shared device' it makes no distinction as to whether a server or a workstation. A device in that context is a single piece of tin and according to the license to run multiple versions of Office for multiple users on that same piece of time you need shared computer activation which doesn't come with Business Basic. Again, I don't make the rules here but shared activation is not limited to terminal servers, it applies everywhere. per the link I quoted:

Shared computer activation lets you deploy Microsoft 365 Apps to a computer in your organization that is accessed by multiple users. Here are some examples of supported scenarios:

• Three workers at a factory share the same physical computer, with each worker using Office on that computer during their eight-hour shift.
• Fifteen nurses at a hospital use Office on ten different computers throughout the day.
• Five employees connect remotely to the same computer to run Office.
• Multiple employees use Office on a computer that's located in a conference room or some other public space in the company.
• Multiple users access an instance of Office that is hosted through https://docs.microsoft.com/en-us/DeployOffice/deploy-microsoft-365-apps-remote-desktop-services.
