I'm trying to use the command below out of Sams - Microsoft Exchange Server 2007 Unleashed, but I'm receiving 'Invalid Namespace'. Does anyone have any idea how to resolve this? get-wmiobject -class exchange_mailbox -namespace root\microsoftexchangev2 -computername xxx | select-object mailboxdisplayname,totalitems,size | sort -descending "Size" | select-object -first 25 Thanks Dennis

Exchange 2007 Does not support WMI Use Exchange Command Console instead! http://www.exchangeninjas.com/Programming Deli
