 > [!IMPORTANT]
 > When you update system properties through rule actions, it might change the expected behavior. Some properties are only evaluated when a message is received in a queue or a topic. Therefore, when you update these properties in a rule action and then deliver them in a subscription, they're ignored. Although when auto-forwarding to another queue or topic, they're reevaluated.
