Outlook email no longer working

Hi,

I am repeatedly being prompted for username and password in Outlook. I was using Outlook just fine a few days ago.

I have verified the settings using https://www.xfinity.com/support/articles/email-client-programs-with-xfinity-email.

I can login fine using the browse, but outlook is not working.

I have deleted the outlook cache files and even the account info to try and restart, but it has yet to work.

Here is a log from outlook:

I know the username and password is correct, so I am confused. 

I enabled logging so we can direct this to higher level support as soon as possible.

Thanks
