Deleting a policy group does not delete its policies. It also does not unenforce the policies from devices where they have already been enforced. To unenforce the policy from devices, remove the assignment of each policy from the devices before deleting the policy group.
For information on unassigning policy from a device, see Section 3.9, Unassigning a Policy from Devices.
To delete the policy group:
In Endpoint Management Console, click the Policies tab.
In the Policies list, select the check box next to the policy group (or policy groups).
Click Delete.
