This is caused by a bad contact record. The record may be located in your Outlook contacts, on your mobile device, or both. All email messages sent from the hosted Blackboard system have appended to the address as shown below.

Under certain circumstances a record with the “do-not-reply” email address may be added to your personal contact list. In this situation the invalid address will be used for all subsequent replies to Blackboard emails, generating the delivery failure.
