I assume that in bigger organizations most mail stored in IMAP storage
is internal. I also assume that size of typical mail in "unix/linux
culture" and "MS culture" do differ. It may explain quite different 
experiences.

Could you elaborate about penetration by MS software/culture (especially
about MS Exchange) in your university?

BTW I have seen a few (smaller) organizations with most (internal) mails
below 4KB but remaining *huge* mails capable to very significantly
influence average size. It makes me doubt about value of 
*bare* "average email size".

P.S. Anyway many organization are legally obliged to archive all emails.
