Same problem here. When using OWA, students are offered unsubscribe option (Getting too much email from ***? you can unsubscribe) appended to every email.
List-unsubscribe header was also removed from such emails, but the unsubscribe option is still there.
University Administration is definitely against offering students or staff an unsubscribe option which may be actived by mistake - touch screens are often the culprits in this case.
We are talking about one hundred thousand accounts here, so manual management is not doable.
