Can you delete unwanted Active Directory Groups in Directory Groups from the Mimecast Administration Console?

In the Mimecast Administration Console, the functionality related to Active Directory integration does not allow for the deletion of Active Directory Groups directly. This is because Mimecast primarily acts as an email security and management layer that interacts with Active Directory but does not alter the underlying Active Directory structure.

Mimecast synchronizes and manages groups from Active Directory for email filtering and other services, but any changes to group memberships or deletions must be conducted within Active Directory itself. Thus, an administrator will manage group life cycles, including deletions, through Active Directory systems rather than within Mimecast.

This design keeps the integrity and security of the Active Directory environment intact, emphasizing that Mimecast is not a management platform for Active Directory objects but rather a companion service that enhances email security based on that directory's structure.
