You can configure your Yahoo account on any email client by POP or IMAP as the incoming mail server and SMTP as the outgoing mail server. To configure the Yahoo account on Outlook, use Yahoo Mail POP and SMTP settings for Outlook. The POP setting lets you access your Yahoo account on a desktop or mobile app. The email messages will be saved to the local email client if POP is used as the incoming mail server protocol.
