Outlook Error 550: Relay not permitted
If you are getting “The server responded: 550 Relay not permitted” on your Outlook, you may want to check the following settings:
1. SMTP Port Number
Make sure the SMTP port number is 587, and not 25.
2. SMTP Authentication
Check and make sure the “My outgoing server (SMTP) requires authentication” and “Use same settings as my incoming mail server” options are selected.
3. Verify Settings
Check if your email settings are correct. You can refer to Outlook IMAP settings or Outlook POP3 settings.
