Hi Codev! I moved this reply of yours into a fresh Support topic so we can help you look into the problem you are having which appears to be specific to your setup.
I think what you want to do is clear the POP3 polling username and POP3 polling password. Then you can disable the POP3 polling enabled setting. Can you try that?
Were you able to get it resolved in the meantime? Any new info you can provide?
