Then all of a sudden all of my outgoing emails were sitting in the Outbox. Processing....processing.....processing.....ERROR. Even emails going to ONE email address would not get sent. Now I can't get ANY emails to send !!!!!! I've checked my settings recommended by cox on forum. I wasted SO MUCH TIME going back and forth on my Outlook 2016 and myemail.cox to send out emails because not all of my email addresses are on myemail.cox. All of these troubles started when the security settings changed. Maybe it's time to change internet service! CAST Re: MS outlook email problem I have updated the required security settings.A few weeks ago I spent 4 days trying to get my outgoing mail to send mail. I reached tier 2 and finally got things to work after simply changing my password. Now, a few weeks later, my outgoing mail suddenly continues to show error message 0x80042109. One minute my outgoing mail was being sent and the next moment it stopped. I use Outlook 2016 (Office 365). I know there are no issues with my online cox account because I can send and receive mail on the cox website, but all of my contacts are in Outlook. Cox needs to fix this outgoing mail issue with Outlook. Everything was working fine until I changed the security settings. WHAT IS THE ISSUE COX?!!!! This is getting old - fast.
