Probably you need to restore it first and then see the size. Hopefully Ill get corrected by someone who knows more.

That's rights there no CMD to check mailbox statics of the inactive mailbox, what other than restore you can try is E-discovery search that should be able to tell how much items are in there and what is their size.

below link is for pst export but you can follow the steps upto the search result info.

Get-MailboxStatistics inactive -IncludeSoftDeletedRecipients | fl
