Hello! One of the features i find interesting (with Exchange in particular) is that you can have a single file for multiple users; i.e. when one sends a message with a large attachment, you end up with one copy of the attachment to which the recipients all have access to, as compared to conventional MTAs where you end up with multiple copies. Disk space-wise, it's not very efficient.
