Unable to connect Outlook using POP or IMAP instructions for Yahoo Mail. It appears Yahoo is not set up for Outlook to connect our Cox.net email accounts to their POP or IMAP servers (pop.mail.yahoo.com or imap.mail.yahoo.com). Suspect the servers are rejecting anything that isn't a yahoo.com extension. One would of thought Yahoo would have planned for this ahead of time for the Cox.net extensions. When I was able to talk with a person, their suggestion was to wait 24 hrs. and try again. i.e. trying too soon after the switchThe switch to Yahoo mail is anything but good. Since switching, about half the time Yahoo is not available and/or takes repeated logins. Yahoo's AI chat bot (AKA Help) is not set up to be much assistance to those with a Cox.net extension. Yahoo wants you to pay for premium service to resolve all but the very basic issues. Always referring you to a tutorial on Yahoo's help page.... which most have already looked at before starting a chat.

This looks promising... https://www.ubackup.com/articles/yahoo-mail-not-working-with-outlook365.html#:~:text=Why%20is%20Yahoo%20mail%20not,an%20app%20password%20for%20Outlook.Haven't had a chance to try it yet... won't have time for that for a few hours.

I am having the same issue with Mail on my Macbook. I've deleted, re-added, used the correct server settings, etc. - nothing works. It says my account and the servers are 'offline'. I had to use the Yahoo mail app, which I don't like as much as macmail. If anyone has had success with this it would be much appreciated.
