My experience with Outlook is limited to disabling it as far as possible! I use Yahoo mail however. This is the nitty gritty:
SMTP server: pop.mail.yahoo.com
SSL enabled
port 465
mail plus
SMTP server: plus.smtp.mail.yahoo.com
SSL enabled
port 465
Use authentication
Account Name/Login Name: Your Yahoo! Mail ID (your email address without the "@yahoo.com", for example, “testing80”)
Email Address: Your Yahoo! Mail address (for example,
[email protected])
Password: Your Yahoo! Mail password
