• Answer:

  Unfortunately, there are lot things that could cause difficulties with POP access. We've outlined most of them below: Subscription to Yahoo! Mail Plus Service: You must subscribe to the Yahoo! Mail Plus service for POP access through your email client. POP Access Option: Click Options in the upper-right corner of your Mail page and select Mail Options. From the list on the left, click POP & Forwarding, then Set up or edit POP & Forwarding. Now: is there a dot in the circle beside "Web & POP Access"? If so, great! If not, that means there's a dot in the circle beside "Forwarding." Your account's NOT POP-enabled whenever you select the "Forwarding" option, because these two separate features can't be used at the same time. If you make a change here, make sure to click Save when you're done. Client Settings: Is there a problem with your email client settings? Please make sure that you've configured your email client with these settings: Incoming Mail (POP3) Server: plus.pop.mail.yahoo.com (Use SSL, port: 995) Outgoing (SMTP) Server: plus.smtp.mail.yahoo.com (Use SSL, port: 465, use authentication) Account Name/Login Name: your Yahoo! ID (your email address without the "@yahoo.com") Email Address: your Yahoo! Mail address (e.g., [email protected]) For information on entering these settings into various email clients, read the POP – Mail help section. Set Up Have you selected an incompatible log-in method or server type when you set up your email client? To check your settings, please follow the steps below for your email client.
