    • Problem is, Get-MailboxStatistics output just a display name – not unique and cant really be used as such. The other half of the information you need is in Get-Mailbox :- found answer in following link. once you have the data on all your mailboxes, and the output can be IMPORTED into excel you can do all your sorting etc and delete whatever you dont want

      ***if this is what you were looking for, please click this link and give the guy some credit.. i didnt come up with this, i just found it

      #REM http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_27828458.html

      $Mailboxes = Get-Mailbox -ResultSize Unlimited
      foreach ($Mailbox in $Mailboxes)
      {
      $Mailbox | Add-Member -MemberType “NoteProperty” -Name “MailboxSizeMB” -Value ((Get-MailboxStatistics $Mailbox).TotalItemSize.Value.ToMb())
      }
      $Mailboxes | Sort-Object MailboxSizeMB -Desc | Select PrimarySMTPAddress, MailboxSizeMB

      #REM – to export this out — do the following 😉 enjoy (see the part where it says “Select” you can add additional fields like ALIAS etc to this)

      $Mailboxes = Get-Mailbox -ResultSize Unlimited
      foreach ($Mailbox in $Mailboxes)
      {
      $Mailbox | Add-Member -MemberType “NoteProperty” -Name “MailboxSizeMB” -Value ((Get-MailboxStatistics $Mailbox).TotalItemSize.Value.ToMb())
      }
      $Mailboxes | Sort-Object MailboxSizeMB -Desc | Select PrimarySMTPAddress, MailboxSizeMB | Export-Csv -NoType “C:\temp\Mailboxessize.csv”
