An Approver is a person authorized by an AGPM Administrator (Full Control) to create, deploy, and delete Group Policy objects (GPOs) and to approve or reject requests (typically from Editors) to create, deploy, or delete GPOs.
Ensure that you are connecting to the central archive for GPOs. For more information, see Configure the AGPM Server Connection.
Because the Approver role includes the permissions for the Reviewer role, an Approver can also review settings and compare GPOs. See Performing Reviewer Tasks for more information.
By default, the following permissions are provided for the Approver role:
Also, an Approver has full control over GPOs that he created or controlled.
