With a SBS 2011 box (Exchange 2010) there is a user complaining the mail he sent was not received.
He has used delayed send and the items were in the outbox on their Outlook client - they also show in the sent items as sent OK.
Could someone please advise where logs can be found showing the low level status of the delivery of these messages?
How can i tally up the sent item email with the item in the log?
