outgoing mail problem

[dakotajoe]

I am not able to send out email with one of my email addresses (although I can receive emails). When I compose an email and send it, it goes to my outbox and Outlook tries to send it, but it just stays in my outbox and it ultimately times out. I don't have this trouble with any of my other email accounts, including others that use the same isp and server. This just started a few days ago. And here is a strange thing -- when I go into the email settings for this email address, I am able to send a test email when I click on "Test Account Settings".
