RBAC ManagementRules does not apply to Outlook
It should not be possible to Outlook Users to Bypass Management Rules created in Exchange via Powershell.
I created a new Management Rules where the user is not allowed to change the ExternalAudit in MyBaseOptions.
It applies to OWA but if a users uses Outlook he is still able to Change that.
This means that Outlook Bypasses the rbac security model which should not be possible.
