Change the Order of WebBlocker Exception Rules
The order that the WebBlocker exception rules appear in the dialog box shows the order in which sites are compared to the rules. WebBlocker compares messages to the first rule in the list and continues in sequence from top to bottom. When a messages matches a rule, WebBlocker performs the related action. It performs no other actions, even if a site matches a rule or rules later in the list.
To change the order of rules, select the rule whose order you want to change. Click the Up or Down button to move the rule up or down in the list.
