SMTP error using New Outlook

When is Cox going to upgrade their platform to solve the outgoing email sending error that happens with the new Outlook???

The only way I can send an outgoing email is to exit Outlook and log in to webmail. Your support desk confirmed that Cox is not yet updated to work with the new version of Outlook. VERY ANNOYING.

Technical details

SmtpSubmissionPermanent5XXException: Smtp submission failed. Server 'smtp.cox.net' Port '465'. --> Unexpected SMTP server response. Expected: 250, actual: 503, whole response: 503 not available
 
Failure code: 5513

Hi Jill R.,

I am sorry to hear that you have been having trouble with your email. I have not been made aware of any known issues that we currently have with outlook right now. I would suggest checking the outgoing server settings using the following link. www.cox.com/.../cox-email-server-settings.html .

This is a bs response.  I'm having the same issue now and the only response I get from cox is to use webmail.  This is bs.

I had the same issue with the New Outlook in Windows 10. I was using the recommended settings created automatically by Outlook for Cox and was able to send, but receive NOTHING. So I logged into the web version of Outlook and was able to successfully send. 

When I checked the web settings I noticed the STMP port was 983. I had to delete the account and then change the settings manually when I created it again. This time I set the port to 587 and everything works great now!

Cox doesn't have to upgrade their system to work with the new outlook. As long as the new outlook conforms with RFC specifications for Simple Mail Transfer Protocol, (SMTP), then it will work without issue.

Before doing the below, ensure all email sitting in the OUTBOX is deleted.

Ensure your settings are correct, SSL, port 465, and "My Outgoing Server Requires Authentication" has to be selected. OR. Use TLS, Port 587, and again, "My Outgoing Server Requires Authentication".

As long as your settings are correct, then it will work with Cox, since Cox's servers conform to RFC specifications.

What do you need to look at personally? This is is a known issue. Are you just trying get the bad PR off the forum?

I'm wondering if this was an issue with the servers themselves as after about 48 hours it started working again.
