AssignToCategoryRuleAction Object (Outlook)
Represents an action that assigns categories to a message.
AssignToCategoryRuleAction is derived from the RuleAction object. Each rule is associated with a RuleActions object which has an AssignToCategory property. The AssignToCategory property always returns an AssignToCategoryRuleAction object. If the rule has an enabled rule action that assigns a message with some specified categories, then AssignToCategoryRuleAction.Enabled would be True.
