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 the Incoming mail server Outlook settings.
- If the previous solution does not yield the desired results, an alternative approach to troubleshoot email sending issues is to disable the firewall on your local machine. By temporarily deactivating the firewall, you can determine if it is causing any interference with your email sending process.
- If you have verified that your email accounts are correctly configured and are still experiencing issues, an alternative step to troubleshoot is accessing your mail account through the webmail interface. To do this, follow the provided link: http://mail.yourdomain.com.
- If you cannot access your mail account through the webmail interface, it indicates a server-side issue that requires additional investigation. Resolving such problems may take some time. In this situation, you should raise a support ticket by emailing firstname.lastname@example.org from your registered email address. The support team will assist you in diagnosing and resolving the issue.
However, if you can successfully access your email using the webmail interface, it suggests there is no problem from the server side. In this case, you should contact your Internet Service Provider (ISP) to check if they are blocking ports 25 and 587. These ports are commonly used for email communication, and if your ISP blocks them, it can prevent you from sending emails through standard email clients. Contacting your ISP will help clarify if this is the cause of your email sending issues.
- If you have exhausted all other options and your email issues persist, reinstalling a fresh copy of Outlook is the final recourse. Reinstalling Outlook can help resolve any underlying software or configuration problems that may be causing the issues.
