Which type of user has the highest level of access in an Intune deployment?

In an Intune deployment, the role of a Global Administrator holds the highest level of access among different user types. This role is integral for managing and configuring Microsoft Intune as well as other services within the Microsoft 365 environment. A Global Administrator can perform a wide range of tasks, including the ability to manage user accounts, licenses, security settings, and configurations across all services in the tenant.

This role is crucial for ensuring that all settings are correctly applied and maintained, and it provides the necessary authority to assign roles to others, something that lower-level administrative roles cannot do. Custom Administrators can manage specific areas within Intune but do not have the extensive permissions of a Global Administrator. Regular users have limited access and control over their devices, while Service Administrators focus more on system-level operations without the same breadth of authority that comes with being a Global Administrator.
