If you want to use Outlook, Outlook Express, Thunderbird or other third party email clients to view your email you have 2 options.

Click on YPOPS link on the left.


Then Click on Configuring email clients towards the bottom.


Choose the appropriate link for your mail client.





I currently utilize version 2.0.0.4 of Thunderbird


and version 0.8.3 of YPOPS (there is a more recent version of YPOPS that you need if you are Yahoo Beta Mail) and have no problems.
