How do I change my Yahoo email on my Blackberry?

Need help with setting up my email account on a Blackberry!!?

• I've been able to set up my hotmail account however I have been unsuccessful in setting up my Yahoo mail account. I go through the standard setup procedure on my device, typing in my email address and my password but it doesn't work. I get an email (on my computer): 'If you use an email client (e.g. Microsoft(R) Outlook(R), Mozilla(R) Thunderbird(TM), etc.) to access your [email protected] messages, change your email client settings to leave your email messages on the server. If the email client does not leave email messages on the server, the BlackBerry(R) Internet Service may not be able to deliver them to your BlackBerry(R) device. To leave email messages on your email server you may need to complete the following steps: 1. In your email client (Outlook, Thunderbird, etc.) on your computer, under Tools or Mail > Preferences. 2. Select your email account. 3. Locate advanced, server settings or options. 4. Select the option to leave email messages on the server. Refer to your email client help for more information.' I simply use Internet Explorer to access Yahoo mail, I don't understand how/what action is required. Can anyone help me??? I'll be forever grateful. Thanks in advance!

• Answer:

  If you're using a free ymail account, you need to upgrade to the paid version - Yahoo Mail Plus for this to work. The message you're getting isn't the typical error message in this scenario though. It seems to indicate you have the right type of account but the Blackberry email program isn't finding any messages to download from the server. This happens if you are using a program such as Outlook or Thunderbird and it is set to delete messages from the server after download. Then there's nothing left there to be read by another program.
