What else do I need to know?

• Before you set up a POP3 or IMAP4 e-mail program, you need to look up your own POP3, IMAP4, and SMTP server settings.
  
  Watch this video to learn how to find your server settings for your POP or IMAP e-mail program.
  
  To find your server settings, sign in to your e-mail account using Outlook Web App. After you sign in, click the drop-down arrow next to the Help question mark, and then click About. The POP3 or IMAP4 server name and other settings you may need to enter are listed on the About page under External POP setting or External IMAP setting. The SMTP server name and other settings are listed under External SMTP setting.
  

  Important:
  The following settings are just examples. You must look up your own server settings.

  • If you're using POP and the About page shows the following:
    External POP setting:
       Server name: pod51000.outlook.com
       Port: 995
       Encryption method: SSL
    your POP3 server name should be set to pod51000.outlook.com.
    
  • If you're using IMAP and the About page shows the following:
    External IMAP setting:
       Server name: pod51000.outlook.com
       Port: 993
       Encryption method: SSL
    your server name should be set to pod51000.outlook.com.
    
  • To find your SMTP server setting, if the About page shows the following:
    External SMTP setting:
       Server name: pod51000.outlook.com
       Port: 587
       Encryption method: TLS
    your SMTP server name should be set to pod51000.outlook.com.
    

    Note:
    Write down the server settings in case you need them for future reference.
