What is required to successfully manage directory groups in Mimecast?

To successfully manage directory groups in Mimecast, synchronization with an external Active Directory is essential. This synchronization allows Mimecast to align its directory structure with the organization's existing user database, ensuring that changes made in the Active Directory, such as the addition or removal of users and group changes, are reflected in Mimecast. This feature not only streamlines user management but also enhances the efficiency of email security and compliance policies by maintaining accurate and up-to-date group memberships.

While having admin access, knowledge of DNS configurations, and an understanding of organizational policies can contribute to overall successful management and a better user experience, they are not specifically required for managing directory groups within the Mimecast environment. These factors support the broader administrative context but do not directly influence the core functionality of syncing directory groups with Active Directory.
