What triggers the need to upgrade from Azure AD Free edition to Premium edition for a customer using Microsoft 365 and Azure subscriptions?

Upgrading from Azure Active Directory (Azure AD) Free edition to the Premium edition is often necessary when customers need advanced identity and access management features, particularly concerning role-based authorization. The Premium edition offers enhanced capabilities, including advanced security reporting, identity protection, and dynamic groups, which are integral for organizations requiring detailed control over user roles and access permissions.

Role-based authorization enables organizations to define specific roles within their applications and enforce policies based on those roles. This is particularly important for organizations transitioning to more complex IT environments, where having granular control over who can access what resources is critical for maintaining security and compliance.

In contrast, while support for external IDs, access to premium applications, and increased storage capacity may offer benefits, they do not directly drive the need for an upgrade as fundamentally as the requirements around role-based authorization. The Premium editions specifically enhance the ability to administer user access based on roles, making it a key reason for businesses to consider this upgrade when their security needs grow more complex.
