I have an Exchange 2010 server environment (2 servers with all roles on each). The other day, I found 2 1.7GB emails stuck in queue. I have restrictions in place (100MB for internal emails <receive connector> and 35MB for external emails <send and receive connectors>) and they appeared to be working fine. My question is "How did the 1.7GB emails (single PowerPoint attachment) make it to my queues?. Is there something that I'm missing with the connectors? These were internal email attempts, but well over 100MB. Also, associated with this, is there a way to make Outlook prevent (or at least warn against) excessive attachments? Obviously, nobody should be sending 1.7GB through email.
I appreciate any assistance provided.
