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.
