I have an issue where an email from an external source seems to get caught in the Exchange Categorizer, and never gets delivered to the Exchange recipient. I have no idea where to look? I have checked the BadMail folder, but there is nothing there for this particular message, nothing in any queue, or the pickup folder. Where did it go?
So far I have only been notified about two instances from one sender, but we cant seem to recieve email from this person?
