Check whether the recepient is valid or not.
Also make sure that Popcon is working normally.
I have seen this type of issues with Popcon before.

Verify whether the settings are correct or not.

Just wondering if Popcon is for sending emails as well? as far I know it is only for retrieve emails ....correct me if I am wrong

Where as the error No AUTH is generally authentication error, check account settings in your email client or enable outlook logging and check the logs if that directs you to the root cause
