When I run "exchange system manager" in Exchange 2003, and going to Server > First Storage Group > Mailbox Store > Mailboxes. Then it may show many items of different mailbox in one screen. Eg. Size, Total Items, Last Login Time, Last Logoff Time .. But when I run "Exchange Management Console" in Exchange 2007, it only can show one mailbox in one screen.

Hi, I believe the topic you've selected to write is "Where are all the mailbox access and size information in Exchange 2007?" you need powershell to view these values with Exchange 2007. here's a nice article for you to read and with examples to how retrieving this data: http://exchangepedia.com/2008/07/where-are-mailbox-last-logon-client-ip-address-and-other-details-in-exchange-2007.html Good Luck !

Thanks you. I got the information.
