Evault Auditing data

We are working on our retention policies and was wondering if the auditing would.  It is my understanding that I can see how often users use their archives but can I see more detailed infomation.  Can I track the dates of the message being retrieved?  Reason is that users may state that they need for example a 5 year archive retention, but is that based on the fact that they actually retieve dtaa that old or do they just want the comfort to know that it is there aka hoarding mail.

Thanks
