Something went wrong and your message couldn't be delivered. This could be a temporary issue. Try resending the message in a few minutes. If that doesn't work, forward this message to your email admin.

For Email Admins
The message couldn't be delivered because a mail routing loop was encountered. This may be due to a routing misconfiguration in the mail flow settings for either your organization or the recipient organization. If mail flow settings were recently updated, this error may be temporary.

Check the message headers in the section below to determine where the loop may be occurring and if it's something you or the email admin for the recipient organization can fix.
