Question on a non delivery receipt. My boss received the email receipt below (1^st one) which is fine as the guy no longer works there. But the area of concern is highlighted. It states another person in the company. He is not listed in the email address area. I did a test on the email to see what I would get. That is the second one below. I havent seen this before do you have any idea why this would show this way? Just want to be sure that person is not receiving any emails that my boss sends or receives or done something that I should further investigate.

Hi,

As a test, please try sending multiple emails to the recipient, does it always state the same highlighted user? If yes, I suspect the highlighted user may have been set as the recipient's delegate.

Please detail your environment a bit if possible, are you using Office 365 or Exchange on-premise? Office 365 users may get the error in the scenario mentioned in this kb below:

"Delivery has failed" and "550 5.1.1 RESOLVER.ADR.RecipNotFound" NDR after a mailbox is moved to Office 365
