Hello,
I found my Verizon email (POP3) was unable to send emails on outlook. At first, I was able to receive, but after following some forum instructions for the error (0x800CCC80): for example, I changed the incoming and outgoing POP3 servers to pop.verizon.net and smtp.verizon.net respectively, I changed the incoming port to 995 and outgoing to 465, I verified my email and password through a browser login, and I tried checking and unchecking the "My server requires SMTP authentication" using the same settings as my mincoming mail server. Finally, I tried removing the email from the email tab on my account settings and adding it again. Now I can no longer receive errors either. In fact, it will not let me add the new email settings at all. I think my incoming and outgoing servers were different before I changed them, butI cannot remember what they were. I logged into my Actiontec GT784WN and verified that Firewall was set on low. Can anyone provide any guidance regarding this issue?
