Hyper-V VHD File Size - Post Shrink and Compact

I have a Virtual Machine that was initially created at 500GB VHD file which ended up being waaaaay to big for the purpose of the server (MBX Server hosting about 100gigs of mailboxes.) After going through the Shrink process the server is now down to just a 200gig partition with 300 gigs of unallocated space in Disk Management. I then powered down the server and went through the Hyper-V compact process and after it finished the VHD file is still at 400gigs in size.

1. What can I do to get the VHD to compact down to the actual usage size within the VHD which is approximately 130gigs of the 200gig partition?
2. Is there a way to remove the 300gigs of unallocated space that is just lingering within the VHD?

Thanks ahead of time. I appreciate any answers on this.
