What is a 0x8000000b email app error?

Syncing your email is a simple process, but you might run into some issues. Windows Mail app Error 0x800c000b results from an issue with the connection between your device and server caused by incompatible security protocols or TLS versions. Incompatible security settings could also be responsible for this error.

What causes the Mail Error 0x8000000b?

1. POP or IMAP is not enabled

  • You are likely to face this issue if your Post Office Protocol (POP) and Internet Message Access Protocol (IMAP) settings are not enabled in the email server.
  • Enable TLS in your email server. The minimum required version of TLS is Version SSL/TLS v12 and protocol-v16 or newer. Older versions might not be compatible with the latest security standards, so don’t forget to upgrade if you’re responsible for managing an email server! This will allow it to communicate securely using encryption protocols designed by the internet engineering task force (IETF).
  • This should fix POP, IMAP & SMTP connection issues resulting from incompatible security settings on the device or within the mail servers themselves.
  • If option one doesn’t work simply disable all nonessential services that are enabled which may conflict with others.

2. Windows Firewall blocking the request

  • According to Microsoft, this can happen if your firewall is blocking the request sent by the Mail application.
  • If option one doesn’t work simply disable all nonessential services that are enabled which may conflict with others.
  • The Windows Firewall might be blocking the request sent by Mail app and thus solving this issue requires disabling all non-essential services that you don’t use in order for them not to interfere with other applications on your PC such as antivirus software or security suites. This will allow it to communicate securely using encryption protocols designed by IETF internet engineering task force (IETF).
  • This should fix POP, IMAP & SMTP connection issues resulting from incompatible security settings on the device or within the mail servers themselves.

3. Third-party Antivirus or Windows Defender

  • If you are using a third-party antivirus or your Windows Defender is enabled, these software could potentially be the cause of the error.
  • If option one doesn’t work simply disable all nonessential services that are enabled which may conflict with others.
  • Third-party Antivirus and other security suites often block different connections to prevent malware from infiltrating your computer, so it’s possible they might interfere with this process and need to be disabled for them not to interfere with Mail app connection requests when sending emails in Windows Operating System (OS). This will allow it to communicate securely using encryption protocols designed by IETF internet engineering task force (IETF).
