Once I received the email from Cox telling me it was now time for me to transition to Yahoo Mail (around March 14, 2024), I used the IMAP settings at https://help.yahoo.com/kb/devices-sln3697.html. I immediately transitioned and it has worked perfectly since March 14th. I can now send and receive my cox.net email using the Outlook email client (both traditional and "new" Outlook). The key to successfully setting your Cox.net email up in Yahoo Mail lies in whether your Cox.net data has been MIGRATED to Yahoo Mail yet. If it has not, you can try to set up the email client you're using all day long and you WILL NOT successfully log in to the Yahoo Mail servers. Yahoo Mail has to be able to recognize your Cox.net email address and can only do so once Cox has migrated your data to Yahoo mail.

Thanks for confirming that this transition can work successfully with the specific steps you described. I am still waiting for the "moved" email (last email I received 3rd email dated Feb 2/19 ("home stretch few weeks)). I use pop3 with Outlook email client (with x6 accounts); it should be straightforward as you described. Hopefully.
Thanks again.
