Exchange 2013 Hybrid - How do I check the MailboxStatistics of an In-Place Archive hosted in O365 for a User with an On-premise Mailbox?

We have Exchange 2013 on-premise with In-Place Archives hosted in Office365.  I want to run get-mailboxstatistics against my hosted archive to check out statistics on the user of the archives.  

I've connected to O365 with a new-pssession and imported the msonline module in PowerShell.

However, I get this error:

[PS] C:\Windows\system32>Get-Mailboxstatistics blahblahblah -archive

"The user 'blah blah blah' has a cloud-based archive. Currently, you can't run Get-MailboxStatistics -Archive on a
cloud-based archive."

Any ideas?
