outgoing email no longer working

I am having the same problem, except I a m using Outlookj.

I changed password and waited, but still not working.

I have the same frustrating problem off and on now for months, on my iphone, ipad, and iMac.  I have tried I think everything that others suggested, including calling Cox (2 hours), and even if the problem randomly disappeared as mysteriously as it appeared, I cannot get it fixed for good.  Its very frustrating and the only consolation is knowing that I am not the only one.  I believe it is a Cox issue and Cox should look into it and fix it for good!

hmmmm.... no response!  why is this called a support forum if support isn't given?

Why does cox send out instructions on changes but not give complete instructions?

Got mine working on thunderbird.

  ssl for outgoing.  Auth. method is normal

password is your password for you cox email  and user name is the main username for you cox account. 

So each individual email address if you have multiple will have the same username and password as you use for logging into cox website.

I understand you are no longer supposed to use the .east. or .west. for cox.  I've read that but can't find it right now explicitly stated

Try smtp.cox.net for the smtp server.  Same goes for pop.cox.net or imap.cox.net

Same problem here. Can receive but can't send (three email addresses). I'm using Thunderbird.

OMG we just got off the phone with the rocks on their phone support.  Their answer is we are the ONLY ones they haven't been able to help, and that we need to contact OUTLOOK. .   I specifically asked about 2016 Outlook being the issue.  the level one support told us no there are no issues with that.   We asked for a level 2, he said he had to ask his supervisor, and came back on and said NO, they would just hang up on us, per his supervisor ROBERT!  

can we get someone that knows how to fix the issue???  and how the *** does someone work a support desk and never touched/looked at OUTLOOK???

i've had this problem twice lately, including this week and it turned out not to be the settings, but the certificates.  i use eudora (yes, STILL!) and i believe qualcomm abandoned that to thunderbird & they are somewhat the same. atlanta keeps changing what they will except (i keep having to mark new ones as "trusted") AND not accepting my saved password, & since i have to actually send an email to be able to even see what ports i'm using, it's been a problem.

if any of this makes sense to the thunderbird people here & want more info on the "how," i'll check back.

johnathon...

i have no problem.  know how to manipulate my client & got it fixed.  please don't mess me up fixing for the others!
