Fixing Windows Live Mail Error Code 0x800CCC6F in Outlook (2010–2016)
Email error 0x800CCC6F in Windows Live Mail or Outlook typically appears when the mail client fails to establish a connection—often due to incorrect server settings, blocked ports, or issues with SSL/TLS protocols. This interrupts sending or receiving emails and can impact your daily communication. To resolve it, follow these steps:
- Verify Server Settings & Ports: Double-check your incoming (POP3/IMAP) and outgoing (SMTP) server details, ports, and encryption settings. Common settings include port 993 with SSL for IMAP or port 587 with TLS for SMTP.
- Temporarily Disable SSL Verification: In the account’s advanced settings, try toggling SSL/TLS off to test connectivity—sometimes certificate mismatches cause the issue.
- Check Firewall/Antivirus Settings: Temporarily disable or adjust firewall and antivirus to ensure ports 993/587 aren’t blocked.
- Repair or Recreate the Email Profile: Remove and re-add the affected account in Windows Live Mail or Outlook to refresh connection data.
- Test Internet Connectivity: Restart your modem/router, switch to a different network, or try Ethernet to rule out local connection problems.
- Update or Patch the Client: Install the latest updates for your email client—especially in legacy versions like Outlook 2010–2016—to ensure compatibility with modern mail servers.
Once complete, restart your mail app and attempt to send/receive emails again. For a full, step‑by‑step walkthrough including screenshots and advanced troubleshooting, refer to this detailed guide. Report this page
