External email arriving in wrong mailbox

[rickyj99]

I have come across a rather odd user query. An external email was sent addressed to person A as joe.adams@abc.org.uk (this was person A's correct SMTP address) but actually arrived in person B's mailbox. I checked in Xchg Admin on both mailboxes and there are no alternate recipient rules set up. I asked person A if he has any rules set up in Outlook to move inbox messages to person B and the answer is "no". I have asked person A to double check his Outlook rules - in the meantime, does anyone have any theories as to why this may have happened?

An explanation has come to light. Person A didn't have any rules set up in Outlook. It has transpired that the sender had set up an address book entry with person B's SMTP address in the address box but, somehow, put in person A's SMTP in the display name box which is why it looked as if the email had been addressed correctly.

Sorry if this has wasted anyone's time.
