If these users only log into this station & do not have personal email accounts I think you can accomplish this.
I assume that there are not 100,s of users.
If each user log on with their own name, there will be a profile for each user, edit their OE status to point to a specific location for the mail.
i.e. I have moved my OE mail files to a dir- 'mymail' and OE has been set to locate mail there.
Redirecting each users OE to find mail at a common location is all that I think you need to do.
If they have personal email, it would depend on what their logon script to the domain predicates.
