Being a team member of admin depart in my organization, I deal with various exchange server activities everyday. Thus, I always need to closely monitor the whole emailing system for enhancing the performance of my organization and convert them into business. My concern is : How can I track non-business email transactions received or sent by individual users on exchange server? I need to monitor for various departments users. Please suggest me.

Can you please share : which exchange server you are currently using ?
