HiIn Exchange 2003, it's possible to view the number of RPC calls per mailbox by adding the column to the view of 'Logons' (Admin Groups > Servers> Storage Group > Mailbox Store > Logons).I can't see a way to do this using Exchange 2007...does anyone know? I assume it is some sort of powershell command?Thanks

Hi Pancamo.Get-LogonStatisticsdoes similar job in Exchange 2007.Get-LogonStatisticshttp://technet.microsoft.com/en-us/library/bb124415.aspxHere is some info and comparison with Exchange 2003...Where are mailbox last logon, client IP address, and other details in Exchange 2007?http://exchangepedia.com/blog/2008/07/where-are-mailbox-last-logon-client-ip.htmlAmit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com

Excellent, I think the Get-LogonStatistics will show the info. I should have remembered that :)Do you by any chance know how to change the view so that the output shows the users with the highest number of RPC calls first?

Hi Pancamo,I didn't get chance to test this in my lab but it should be something like below...Get-LogonStatistics -Server ServerName | Group UserName | Sort -Property Count-DescendingAmit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com
