Original Outage Message:

Washington University Information Technology has detected an issue where emails sent to external email addresses (non @wustl.edu) are bouncing back and not being delivered. Senders are receiving error messages similar to the example below. We are investigating the issue, actively working with Microsoft, and will provide updates as they become available.

Example error message: “Your message wasn’t delivered because the recipient’s email provider rejected it.”

We appreciate your patience as we work to restore service.
