I have been all through the link from Microsoft about how to use Queue Viewer with no help at all:
My problem is this. I have a message stuck in the "Submission" queue for a journal entry, and it keeps throwing errors to my Event log. But when I try to following the instructions above from Technet on removing a message from a queue, I do NOT get the option of "Remove messages (with NDR)" or "Remove messages (without NDR)" when I select the Submission queue.
So, how in the h**l can I clear this message from the queue so that I do not get those Event ID 9213 errors in my event log?
