On May 12th I was unable to send emails under Windows mail. It would come back with an error message of "0X800CCC0F". In my account I'm using (POP3) incoming.yahoo.verizon.net and (SMTP) outgoing.yahoo.verizon.net.
My SMTP port is 25 and my POP3 port is 110. I receive emails but can't send any. If I go to Verizon's email site I can send myself emails and receive them. I don't like Verizon's setup so I've used Windows Mail with Vista and Outlook with Windows ME without any problems. I've tried changing port numbers and checking and unchecking SSl and SPA until I'm not quite sure where I was originally. Something must have changed 5 days ago but I not sure how to fix it. Any suggestions would be most gratefully received.
