Can't Send Emails from Outlook

Level 2

I can't send email, upon checking, below is the error encountered
Task ' - Sending' reported error (0x800CCC78) : 'Cannot send the message. Verify the e-mail address in your account properties. The server responded: 535 5.7.8 [TPG-A02] Authentication denied. User is banned from using SMTP AUTH due to previous abuse'.

I already changed my password, and scanned for possible virus but still didn't solve my problem. Kindly advise. Thanks.
