Search and delete by MessageClass

Is it possible to do a search-mailbox on messageclass??

I am trying to create a search and delete command that I can run on MessageClass IPM.Note.AppliedVoiceTechnology.VoiceMessage for a time frame, month of October.

I think it is something like this...

search-mailbox -Identity USER01 -SearchQuery 'MessageClass:IPM.Note.AppliedVoiceTechnology.VoiceMessage',"Received:> $('10/01/2012') and Received:< $('10/29/2012')" -DeleteContent

Can someone let me know if this is possible or not. And help me with the correct command. I've seen some old articles saying this is not possible.

Thank you much
