I am trying to add threat overrides on the overrides tab of the 'Edit Policy' window in FCS. The 'Add' button is disabled. Is there a setting I am missing somewhere else?
The link correctly helped me to resolve this issue. The Forefront management service was logged in as Local System. I changed it to the Forefront account I created to install the management software then restarted the service. The 'Add' button is now enabled.
