Got an email from someone today saying to ignore their earlier email. What email? I looked at the message tracking on the exchange server and there is in-fact a receive event at the right time, with the correct message subject, but no one got the email? The recipients field (in message tracking)is blank, which is why I'm guessing no-one got the email. In-fact there are two email sent from this person this morning without recipient information. All subsequent emails from this sender have recipient information however. I should point out that this is an external email. Has anyone got any idea how this has happened. Is it a fault with the sender, or my exchange?
