How to Connect Yahoo! to the Microsoft Exchange Server
Yahoo! Mail Plus, an add-on service to Yahoo! Mail, lets you set up POP3 and SMTP connections. Enabling these connections allows you to check email on other servers through your Yahoo! Mail client, including Microsoft Exchange Servers. The Yahoo! Mail Plus Service is available through Yahoo.com for a fee of $19.95 per month, as of May 2010 (see Resources). Once your account is upgraded to Yahoo! Mail Plus, setting up POP3 and SMTP for the Microsoft Exchange Server is a snap.
Yahoo! Mail Plus Upgrade
Open a Web browser and go to Yahoo! Mail (see Resources).
Log on to your existing Yahoo! email account.
Click the down arrow next to "Options" on the top right of the screen.
Select the "Mail Plus" link. The Yahoo! Mail Plus Overview will open.
Click the "Upgrade Now" button.
Enter billing information and update relevant profile information.
When finished updating the account for Yahoo! Mail Plus, close the browser to exit.

Type the POP3 address of the Microsoft Exchange Server. This is the same (non-Yahoo!) POP3 address that is configured in the Outlook client for the Exchange Server account. On corporate networks, you can get the POP3 server address from the email server administrator. For public email systems, you can get the server information from customer support or the support website for the email system.
Type the SMTP address of the Microsoft Exchange server. For corporate networks, you can obtain the POP3 server address from the email server administrator. For public email systems, you can get the server information from customer support or the support website for the email system.
Type the Yahoo! email address and name for the account.
Type the password twice to verify, then click "Save Settings." The Yahoo! Mail account is now configured to send and receive email from the Microsoft Exchange Server. In addition, the new email account will appear in a drop-down list as a custom "From" address.
