I have an Exchange 2003 installed and working. However, recently one user is receiving multiple e-mails on a daily basis notifying him of delivery failure. An example of the e-mail message is below:
From: email@example.com [mailto:firstname.lastname@example.org]
Sent: Sunday, June 18, 2006 5:45 PM
Subject: Delivery Status Notification (Failure)
This is an automatically generated Delivery Status Notification.
Delivery to the following recipients failed.
The strange thing is that my user never sent a message to these users. When I look in their sent items, the is no trace of this message being sent. I have ran multiple virus scans and spyware scans on his local computer and come up with nothing.
Is there any type of report that I can run on exchange to find out where these messages are originating? Any suggestions on how to resolve this issue?
I have 10 other e-mail users and they are not having this problem. They receive the occasion junk mail, but that is it. Please advise.
