We are running Exchange 2010 SP2. Currently if I run the following powershell command Get-Mailbox -Database "Mailbox Database Name" | Get-MailboxStatistics | ft displayname,totaldeleteditemsize,totalitemsize The output I receive for the "TotelDeletedItemSize" is 3.373MB. If I right click my "Deleted Items" in Outlook 2010 I get the reported _Server Data Size_ of 425MB. Right now we permantely delete items in the "Deleted Items" folder every 90 days based on a retention policy. Can anyone tell me why the numbers are different from the powershell command and Outlook?

Can anyone tell me why the numbers are different from the powershell command and Outlook? Because the value reported by the get-mailboxstatistics is the size of the *recoverable* deleted items, not the size of the items that are still visible to you in the Deleted Items folder. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Is there a way to get this same output for every mailbox on the system?
