We have a new exchange server in our organization, and sometimes users report an email that failed to deliver. Typically, I believe that it is related to size or content restrictions from either the firewall or the exchange server itself...
I'd like to know how I can see all failures (rejects, failures, etc) of messages in the Exchange Server... whether looking at log data, or even setting up some kind of notification.
Is this possible in Exchange? Can someone point me to where I'd need to look to set this up or view the failed transactions?
(yes, clearly anything blocked by the firewall will not be recorded in exchange)
