The Outlook can receive email and send out email yesterday. But it can received email and can't send out email today.
When tried Test Account Settings, it’s show the Errors
Send test e-mail message: Unable to send test Message. Please verify the E-mail Address field.
How did you send this "test message" - by composing a new message, or by using the "Test Account Settings" in the mail setup dialog box?
If the former, try the latter and it may throw up a more detailed error message.
