Using classic Outlook for Windows in business environments
Accessing Cox Mail Through Yahoo on Outlook https://youtu.be/m56XSrK-SzI
This will solve your issue
I was hopeful when I saw this video and saw others commenting that it worked for them to get the Cox transitioned to Yahoo email account to work in Outlook. Unfortunately after following all of the steps of changing the server and ports and this time getting a Yahoo generated password for Outlook as suggested by the video, I'm still getting the message that "Something went wrong and Outlook couldn't save your account settings. Please try again." I've retired a few times, but to no avail. Any other suggestions?
