Identifying unmonitored mailboxes

Are there any reports/scripts that could be used to identify potentially unmonitored mailboxes. I was thinking those with no recent access, or a larger than expected unread message count (this could be somewhat unreliable for longer term absence however). If you have had any success in finding unmonitored mailboxes in your Exchange Online tenancy (or on-prem server), any metrics and techniques you used to flag them would be really interesting to learn about. 

  • The email usage reports gives you last access timestamp as well as the number of received/read/sent messages, is that not sufficient?
