Outlook configuration

[Kerplunk]

I am currently trying to configure Outlook to hold all of my e-mails, such as GMail, AOL etc... I have gone into:

Tools - E-Mail Accounts and added the relevant e-mail details.

But, when I try to 'test settings' out of the 5 tests the last one 'send test e-mail' does not work.

Establish network connection
Find outgoing mail server SMTP
Find incoming mail server POP3
Log into incoming mail server POP3
Send test e-mail message

I have set up my correct e-mail address in user information as my "******@gmail.com" address.

The error message I get is -

Send test e-mail message: Unable to send test message. Please verify the E-Mail address field.

Any ideas?
