Sending reported error 0x80042109 Outlook cannot connect to your outgoing SMTP email
The Outlook error 0x80042109 typically means that Outlook is unable to connect to your outgoing (SMTP) email server. This can be caused by a variety of reasons. Here’s how you can troubleshoot and fix it:
Common Causes
Fixes to Try
1. Check SMTP Settings
• Go to: File > Account Settings > Account Settings > select your account > Change > More Settings > Outgoing Server and Advanced tabs.
• Ensure:
• SMTP server is correct (e.g., smtp.yourdomain.com)
• Port is either 587 (with STARTTLS) or 465 (with SSL)
• Authentication is enabled for outgoing server
2. Temporarily Disable Antivirus/Firewall
• Some antivirus programs (like Norton, Avast, etc.) block outgoing SMTP connections.
• Try disabling them briefly to see if the issue resolves.
3. Try a Different Port
• Port 25 is often blocked by ISPs; use 587 with STARTTLS or 465 with SSL.
4. Check Internet Connection
• Ensure you are connected and can browse the web.
5. Test with Webmail
• Log into your email via webmail to confirm the account works.
6. Repair Outlook
