Add me to the list of those with random email failures.. as I too have been experiencing problems. I had a tier 2 trouble ticket open 30 June 2017 and I was to be notified when the problem was fixed,,,,, never heard a thing, yet random failures continued these 3 months. I just dealt with it. Started an inquiry 2 days ago and after an exchange of emails from cox support, I was told the problem was fixed.. yet I continued to get random failures..... Now the tier 3 guys want to reset my passwords (we have 2 email addresses and both experience failures at the same time).
Problem..... there seems to be no change with the issues when initially reported in June and then again in July 2017. I continue to get pop ups asking for user id and password in outlook, Iphone, and Android. I continue to get sending failed on my Android. And I continue to NOT receive all of my email via outlook, Iphone, Android and webmail. I can deal with the random pop ups and sending failures but continue to be concerned about what I am NOT receiving. Reviewing some of the post on the cox internet forums, I see that others continue to have the same issues ....www.forums.cox.com/forums_home/internet_forum/f/aspx?pi58=2
I agree with ExAdmin ... " insufficient server resources" is the issue ....
