How to determine if the Mailbox is Licensed and Unlicensed?

Hi all,

Just wonder if how can I determine if the Mailbox is licensed or unlicensed? and what is the indicator that the mailbox is unlicensed? Since some of my licensed mailbox is inactive but still consuming the license. 

Thank you so much.
