Email Delivery Errors -- When there's a problem delivering an email message that you sent, Office 365 sends an email to let you know. The email you receive is a delivery status notification, also known as a bounce message. The most common type is called a non-delivery report (NDR) and they tell you that a message wasn't delivered. See Email non-delivery reports in Office 365 for more information.
