ITS is currently working with Microsoft on investigating reports of Faculty/Staff receiving undeliverable notifications when sending emails to some students. The undeliverable notifications contain information similar to this:
Diagnostic information for administrators:
Generating server: MWHPR05MB3024.namprd05.prod.outlook.com
Remote Server returned '550 5.2.0 RESOLVER.ADR.MissingPrimary; recipient primary SMTP address is missing: '''
If you receive an undeliverable message containing information similar to the above, please try to resend the email to the student using their full firstname.lastname@example.org email address.
We will provide additional updates once more information becomes available.
