Exchange 2010 - Archiveable TotalDeletedItemSize

Thanks to Rick_2CA - https://gallery.technet.microsoft.com/office/Mailbox-Pre-Archive-347f9162/view/Discussions

I have been able to Modify this script to include: TotalDeleteditemSize and TotalDeleteditemCount

This outputs the below and works exactly how I want:

ItemsCount      
ArchiveItemsCount      
ItemsSizeBytes      
ArchiveItemsSizeBytes      
TotalDeletedItemSize            
DeletedItemCount


The part I am having trouble with, and where I would like a push in the right direction is how to obtain the ArchiveTotalDeleteditemSize & ArchiveTotalDeleteditemCount (The count and size of data that CAN be archived, same as what is output from "ArchiveItemsSizeBytes")

Below is the script, that I have manipulated to include the

TotalDeleteditemSize & TotalDeleteditemCount......

I have attempted to match what was already in the script, by copying the code, and changing the values (Via Powershell ISE), However, I just end up with nothing being returned or getting the identical results as the ArchiveItemsizebytes

Essentially I am after the Archivable size & Count for recoverable deleted items

Any assistance would be greatly appreciated!!!

If I have worded anything wrongly, or something does not make sense, please let me know, and I will be happy to clarify...

# Exchange 2010 Mailbox PreArchive Statistics
# Purpose:  Query mailboxes for mail older than X days in order to plan archive database storage requirements.

## Organizational Management & Discovery Management security group rights are required to execute this script.
## (Note:  I haven't gone terribly far to see what the minimum security rights are.)
## Execution of the script from the Exchange Management Shell (EMS) will provide feedback on execution.

# =================================================
# ==========  CHOOSE CUSTOM SETTINGS  =============

# =================================================

# Set the Mailbox variable to the query you wish to search
# Enable ONE of the following $Mailbox options.  They are ordered in such a way that if two
# options are enabled the last one set will be a smaller set of users than the previous.
## Search a single database (EDIT THE DATABASE NAME)
