552 5.2.0 ESMTP server not available AUP#O-1450 - Time Warner Internet

This question is about "552 5.2.0 ESMTP server not available AUP#O-1450", with Time Warner Cable internet and apps. Hello,



I use Spectrum Business Class email through Microsoft Outlook. Recently, I have been receiving the following error when I send emails through Microsoft Outlook:



552 5.2.0 ESMTP server not available AUP#O-1450



I can, however, reply to emails that have been sent to me, but I cannot send new emails. I am able to send emails via the Spectrum Business Class email website (mail.twcbc.com). I do not receive any errors when I send emails through the website.



Any help out there?

I have been having the same issue with our emails. Except, that I can send new emails but, cannot reply to any without them being kicked back with this error message.
Would be nice if someone could actually help get this resolved.
