This policy setting controls whether shared computer activation is used to activate the version of Office installed on the computer. By default, shared computer activation isn't used for activation.
Shared computer activation is used only for situations where multiple users share the same computer. For example, when using Remote Desktop Services (RDS).
If you enable this policy setting, shared computer activation is used to activate the version of Office installed on the computer.
If you disable or don't configure this policy setting, shared computer activation won't be used to activate the version of Office installed on the computer unless you've enabled shared computer activation by using the Office Deployment Tool or by manually editing the registry.
Note: This policy setting only applies to subscription plans that include Microsoft 365 Apps for enterprise, and to subscription versions of Project and Visio.
