After reviewing all of the posts on this issue we are still not able to resolve our issue.
Users limit is set to 50mb
Receive Connector is set to 200mb
Max Header Size is set to 128kb - Changed from default 64k

A specific domain sends a message that is 13mb and exchange returns it due to the message exceeding fixed maximum message size.

This same domain can send the message to gmail and my user then sends that message to themselves at our organization and is able to receive it just fine.
