If you just want to have outbound mail work from anywhere with minimal effort, get an account with smtp.com for a couple of bucks a month, and set the smtp server to smtp.com.
If you want to really figure out what's happening you should attach the error message you are getting when you send the messages. But I will give it a crack anyway and run over the basics of setting up your email account in Outlook.
Step 1:
From the "Tools" menu, select "Email Accounts"
Step 2:
Select "Add a new email account", and click "Next" .
Step 3:
Select "POP3", and click "Next".
Step 3:
1. All text boxes on this screen must be completed. Your Name: Enter the name you want displayed with your emails.
2. Email Address: A valid email address on your domain.
3. POP3 Server:
4. SMTP Server:
5. User name:
After completing the boxes, click "More Settings".
Step 4:
You clicked "More Settings" which has opened the Properties pages. Click the "Outgoing Server" tab.
Check the box for "My outgoing server (SMTP) requires authentication", and the radio button for "Use same as my incoming mail server".
That last setting might be your issue or it can also be your SMTP server is blacklisted.
What are you using for your SMTP and Mail server?
that is correct setting also check your mail size cause some of the server they have a limit on sending and receiving Email so ask your receiver if they do not have asize limit.
