Two configurations are available in Intune MAM :
Intune MDM + MAM : IT administrators can only manage apps and app protection rules on devices enrolled in Intune mobile device management utilizing MAM and app protection policies (MDM). The Microsoft Endpoint Manager admin center allows customers to manage apps using MDM + MAM.
MAM without device enrollment : enables IT, administrators, to manage apps and app protection policies on devices that aren't registered in Intune MDM. This means that Intune can manage apps on third-party EMM-enabled devices. Customers should use the Microsoft Endpoint Manager admin portal to manage apps that MAM-WE contains. Intune may also control apps on devices that are enrolled with third-party Enterprise Mobility Management (EMM) providers or that aren't enrolled at all.
