Troubleshooting instructions.

If you followed the above configuration steps, you should be all set. However, if you cannot send or receive mail with your email client, try the following tips.

The Yahoo! Mail SMTP server requires authentication. Make sure you have enabled SMTP authentication. To turn this setting on:

1. From the Tools menu, choose “Accounts.”
2. Select the “Mail” tab.
3. Double-click the account labeled “pop.mail.yahoo.com.”
4. Select the “Servers” tab.
5. Check the box next to “My Server Requires Authentication.”
6. Click “OK.”

To control deletion of messages from the Yahoo! Mail Server:

1. From the Tools menu, choose “Accounts.”
2. Select the “Mail” tab.
3. Double-click the account labeled “pop.mail.yahoo.com.”
4. Select the “Advanced” tab.
5. In the Delivery section at the bottom of the window, check “Leave a copy of messages on server” if you want to save your Yahoo! Mail messages on the Yahoo! Mail server as well as on your local computer. Do not check this box if you want your messages to be deleted from the Yahoo! Mail server once you have received them in Outlook Express.

We strongly recommend that you enable SSL for both POP and SMTP, as detailed in the above instructions. This will ensure that your Yahoo! ID, password and email messages are transmitted securely between your mail client and the Yahoo! servers. However, if you choose to not use SSL for SMTP, your email client will likely default the SMTP port to 25. If your ISP blocks port 25 or if you\’re unable to send email, then you will need to use port 587 when sending via Yahoo!\’s SMTP server. To make this change, please follow the directions below:

1. From the “Tools” menu, select “Accounts”
2. Select your Yahoo! POP account and click on the “Properties” button
3. Click on the “Advanced” tab
4. Next to “Outgoing server (SMTP), change port 25 to 587
5. Click “Apply”, then click “OK” and “Close”
