Exchange 2007 Individual Mailbox Size Report

Here is an easy way of listing the mailbox sizes for everyone on your Exchange 2007 mail server. I have not run this on Exchange 2003 so I don't know if it works.

From the Exchange Management Shell run:

Get-Mailbox -server "Exchange Servername" get-mailboxstatistics select-object DisplayName,@{expression={$_.TotalItemSize.value.ToKB()}},Itemcount,ServerName

Be sure not to forget to change "Exchange Severname" the to your server name.

After running the command, I copied it to Excel to create a more user friendly report for distribution.
