The following strange thing is happening. When I use the messagetrackinglogs to select all email sent by me I get a different amount of email back then when I count my sent items in outlook. Outlook has much more items than are returned by the messagetrackinglogs.
I use the following command.
get-messagetrackinglog -Sender "MyEmail@Address.com" -Server "Ex-changeMB/HTServer" -EventID "SEND" -Start "1-3-2011 00:00:00" -End "31-3-2011 23:59:59"
I use this query on every Mailbox/Hub Transport server we have. The total amount of sent items is always less than the items in de folder sent items in outlook.
