Cannot send email!
Has Comcast done something different in the past couple of days that has caused my email to stop functioning?
Cannot send email. No changes have been made to the computer except normal MS updates (Windows 10). It was working fine until yesterday when I began getting popups from my email program that authentication was not needed, or password not accepted, or whatever. The password is fine because I was able to log in and get all my Inbox email. I notice that it logs in but then stalls on authentication and keeps asking for the password. I click the OK box and it just repeats the process over and over again, never connecting with the server to Send the email.
I have tried different SMTP settings and they make no difference. I had been using 465 for the port, but since it stopped working I changed it to 587. That too made no difference. Both POP3 and SMTP have the boxes checked for secure connection. And the log in page has the box checked for "My server requires authentication. I even tried it by unchecking that and that made no difference. I changed the server time out to 90 seconds and that made no difference.
I have tried 4 email programs; the new Outlook Express, OE Classic, Outlook 2016, and Incredimail, all with the same results. I did see that Incredimail failed in its initial attempt to Send a message, but later was able to Send it. Outlook 2016 is set up to SMTP, not IMAP.
I have to resort to using my phone to send email which takes forever, or to sign onto my Comcast account on the web and do email from there. That is not acceptable, but that's what I am forced to do.
