Issue:

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
IMCEAEX
_o=ExchangeLabs_ou=Exchange+20Administrative+20Group+20+28FYDIBOHF23SPDLT+29_cn=Recipients_cn=4e69eb8e7e7a4b46ba559b1c4297137d-studentNetID@namprd05.prod.outlook.com
Remote Server returned '550 5.2.0 RESOLVER.ADR.MissingPrimary; recipient primary SMTP address is missing: '''

Workaround:

If you receive an undeliverable message containing information similar to the above, please try to resend the email to the student using their full netid@masonlive.gmu.edu email address.

We will provide additional updates once more information becomes available.
