same issue here, tried Thunderbird, Outlook and on my cell phone. Can receive, but can't send. I can log on and send/receive via AOL website. I have been on hold with AOL tech support for 15 minutes (800-827-6364)
Am I glad I found this thread--I've been dealing with this all day.
What was weird was that I couldn't send any emails from one computer, but another worked fine, until this afternoon, when it stopped working also.
Hope we get an answer soon!
The problem is still going on here. I tried every and all Outlook / Android setup combo possible and it will just not do it (send emails).
I can and do RECEIVE any of the emails on my devices, but cannot send from any of my four 4 "xxxxxxx@Verizon.net" accounts.
Again, I can go to https://mail.aol.com and login and reply from there (and it works!), but since I am running POP3, those replies will never be added to my Outlook, unless I manually CC myself on every reply.
Verizon / AOL / Yahoo -- whoever, PLEASE get this fixed ASAP!
