Since a few weeks ago I cannot send email from my tpg mail box via Outliook anymore. When I try to send email messages it fails and sometimes it displays message like 'Task email@example.com - Sending reported error (0x800xCCC78): 'Cannot send the message. Verify the e-mail address in your account properties. The server responded: 5126.96.36.199 (TPG-A02) Authentication denied. User firstname.lastname@example.org is banned from using SMTP AUTH due to previous abuse'. Can somebody tell me how to fix this problem to allow me sending email via Outlook again? For information my other family members have alternative tpg email addresses (email@example.com, firstname.lastname@example.org etc) and they do not have issue with sending emails from their tpg mail boxes via the same Outlook I am using.
