Step 1: Start by clicking the Tools link and then click E-mail Accounts.
Step 2: The Email Accounts window appears.
Step 3: Click here to add a new email account. Then click Next.
Step 4: Choose POP3 here. Then click Next.
Step 5: Enter the Name as you would like it to appear in the From field of outgoing emails.
Step 6: Then enter your new email address here.
Step 7: Now enter the email username….. this is the entire email address (email@example.com).
Step 8: Then enter your email password here.
Step 9: Now enter your Incoming (POP3) and Outgoing (SMTP) server settings in these boxes.
Incoming Mail Server: secure.emailsrvr.com
Outgoing Mail Server: secure.emailsrvr.com
Step 10: Click the More Settings tab.
Step 11: Then click the Outgoing Server tab.
Step 12: Check the box for SMTP Authentication. Most SMTP servers use the same username and password as the incoming (POP3) servers, so just leave this selected, then click OK.
SMTP authentication means that Outlook will login to your mail server even when sending emails (not just receiving), ensuring that you are the only one that can send emails from your account.
Step 13: Click Finish to complete the wizard.
That’s it! We’ve successfully setup an email account, and can now start sending and receiving emails to and from that account, from Outlook 2003.
