I have a user that sent an email to 6 people. 3 of them were external addresses, and 3 were internal. The 3 internal users all got theirs, but the sender still got a return.
Typically, at the bottom of the return you get this message:
Your message did not reach some or all of the intended recipients.
Subject: <insert subject here> Sent: 7/27/2010 10:39 AM
The following recipient(s) cannot be reached:
However, there isn't a list of recipients and failure reasons, the email simply ends. How can I go about finding out which addresses failed? I've checked event logs on the Exchange server, with nothing of relevance in there.
This is Exchange 2007 Enterprise on Server 2003
EDIT1: I've already been through the Message Tracking utility. The parameters selected were Sender, EventID = Fail, and todays date. It shows no messages failed.
