Hi,
In the Exchange ECP you can go to the server and then transport limits. Here you can set the option to notify the sender if a message is delayed, we do so after 1 hour. IT also needs to be notified if their is a delay to any messages how can I do this? Is there a way IT can be notified when the queue is backed up because we need to take measures sometimes usually one message is stuck in the queue and hanging stuff up.
