Hello again Joe,
If Yahoo Mail only connects with the new version of Outlook, it’s likely because newer versions of Outlook support more secure authentication protocols that Yahoo (and many other email services) require for added security. To connect your Yahoo Mail to the latest versions of Outlook:
Open Outlook and go to the File menu.
Choose Add Account.
Enter your Yahoo Mail address, and Outlook should guide you through the process, which typically involves entering your password and possibly a two-factor authentication code.
If there are specific requirements or settings needed, Yahoo’s help documentation or Microsoft Outlook support can provide the detailed server settings (IMAP/SMTP) required.
Hope this helps
