SMTP Port: 25 or 587. Send test e-mail message:
Outlook cannot connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).
- Please verify that you have enabled "My SMTP Requires Authentication" in Incoming mail server Outlook settings.
- If this does not work out, then try to disable the firewall of your local machine from where you are trying to send out an email.
- If you find that your email accounts have been set up correctly, then try to access your mail account using the webmail interface. The link is: http://mail.yourdomain.com.
- If you cannot access your mail account using your webmail interface, then your issue requires further investigation from the server-side and may take some time before it can be resolved. In this case, all you will need to do is to raise a support ticket to [email protected] from your registered email address.
However, if you can access your email successfully using your webmail interface, then there is nothing wrong from the server-side and you will need to contact your ISP to check if they are blocking ports 25 and 587.
- In any case, if your issues still remain unresolved, then the last option available is to reinstall a fresh copy of Outlook.
