I have a user who has just reported than an expected e-mail has not arrived.
Normally that's caused by the sender getting the e-mail address wrong but in this case, a check of Exchange System Manager shows that the mail did indeed arrive with our Exchange box.
From there however it appears to have got lost, never arriving in the user's inbox.
I have checked the logs on our Trend Worry-Free installation and nothing show up there (that said, I don't know Trend that well, so I may have missed something)
Any experts have a suggestion as to how I can trace where this e-mail has gone?
