What indicates whether or not the message still exists on the Control or Hold Queue?

The waiting column in the message search is the key indicator of whether a message remains in the Control or Hold Queue. This column provides a direct view of the status of messages, specifically highlighting those that are currently pending or waiting for processing.

When reviewing messages in these queues, the waiting column shows which messages have yet to be addressed or completed. A message that has transitioned out of the Control or Hold Queue will no longer appear in this waiting column. Thus, it serves as a practical tool for tracking the existence and status of messages within the queues, allowing users to manage and process them effectively.

In contrast, aspects such as the status of the message in the database may reflect its overall condition or processing progress but would not specifically indicate whether it exists in the Control or Hold Queue. Similarly, the total volume of messages being processed indicates throughput or load but does not specifically pinpoint the status of individual messages. The unique ID assigned to each message is crucial for identification and tracking but does not convey the current presence or absence of a message in the relevant queues.
