Access reviews
Access reviews are an Azure AD Premium feature. They allow organizations to evaluate access to specific resources or group memberships on either an ad-hoc or scheduled basis. For example, you may want to use access reviews to periodically audit the membership of the Microsoft Teams Administrators group.
Access reviews can be delegated to specific administrators, business owners, or even end users who can self-attest their need to continue to maintain access to a resource. Access reviews also allow administrators to configure automation actions, such as removing users from privileged groups if it is determined that they no longer need that access.
