Removing a Disconnected Mailbox using PowerShell

I am using Exchange 2010 SP1.  While I was setting things up, I created 4 test accounts.  Now that everything is working, I deleted those test accounts from the Recipient Configuration\Mailbox area.  Now they are sitting in the Disconnected Mailbox area.

I found a Powershell script from Technet that I have been trying to use to permanently delete these mailboxes, but cannot get it to work.  The example script is this:

$Temp = Get-Mailbox | Where {$_.DisplayName -eq 'John Rodman'}
Remove-Mailbox -Database Server01\Database01 -StoreMailboxIdentity $Temp.MailboxGuid

However, when I execute these cmdlets the first one executes, but does NOT return the GUID value into the $Temp variable.  And then obviously the 2nd cmdlet fails with the error saying that -StoreMailboxIdentity has a 'null' value.

Does anyone have any experience successfully executing these scripts?  Or does anyone have a better and working method of permanently removing mailboxes from the Disconnected Mailbox area?

Thank you in advance,
Jeff

Listing all disconnected mailboxes
Get-MailboxStatistics | where-object { $_.DisconnectDate -ne $null } | Select DisplayName,MailboxGuid

Removing all users at the same time
$users = Get-MailboxStatistics | where-object { $_.DisconnectDate -ne $null } | Select DisplayName,MailboxGuid
 
Now that we have all disconnected mailboxes in a var, we can run the following cmdlet to remove all of them:
$users | ForEach { Remove-Mailbox -Database "Mailbox Database" -StoreMailboxIdentity $_.MailboxGuid -confirm:$false }

vicoso,

I get an error on the cmdlet of Get-MailboxStatistics, on the "where-object" parm.

I tried using both "where -object" and "where-object" (thinking I needed a space between the dash and the where).

The error(s) I get are as follows:
(Using 'where-object'): Where-Object : A positional parameter cannot be found that accepts argument 'Select'

(Using 'where -object'): Where -Object : A parameter cannot be found that matches parameter name 'object'.

Any suggestions?

Thank you,
Jeff
