I have successfully synced my tasks and calendar between Outlook 2003 and
Yahoo. I have also forwarded emails from Yahoo to Outlook so I am getting
the incoming emails but if I send an email, it does not sync.

Is there a way to sync both incoming and outgoing emails between Yahoo and
Outlook 2003?

Also, I am using the Business Contact Manager in Outlook. Yahoo is only
syncing with the personal contacts, not the business contacts. Is there a
way to sync Yahoo and my Business Contacts?
