RuleActions Object (Outlook)
The RuleActions object is a fixed collection. RuleAction objects or types that derive from the RuleAction object cannot be added to or removed from the RuleActions object.
The Rules object model provides partial parity with the Rules and Alerts Wizard in the Outlook user interface. It supports the most commonly used rule actions and conditions. Although it does not support creating rules with any rule action or rule condition that the Wizard supports, you can still enumerate and enable these rule actions and conditions in existing rules.
