Exchange 2010 - total size consumed by mailbox retention policy

I am being asked to bump up the deleted items retention policy on our Exchange Environment from the default 14 days. I need to evaluate the current amount of space taken up by the retained deleted items for 30, 60 and 90 day intervals.

So I am trying to get a baseline for how much space is being taken up currently.

I have tried looking at the following perfmon but the counters show 0:

MSExchangeISMailbox: Total Size of Recoverable Items

and I have attempted this Powershell the created .csv also shows 0.
get-mailbox -resultsize unlimited | Get-MailboxFolderStatistics | where{$_.name -like "deleted* "} | ft identity, FolderAndSubfolderSize >c:/report\report.csv

I have looked at several mailboxes through OWA and verified that there are recoverable items as far back as 14 days so I should be seeing some storage being used.

Thank you the original command came up with zero's again but looking at the link I was able to put together this command which got me what I wanted:

Get-Mailbox -Server 'ServerName' -ResultSize Unlimited : Get-MailboxStatistics -FolderScope RecoverableItems | Sort-Object FolderSize -Descending:FT Identity, FolderSize, FolderType
