Why Does Error Message 0x800ccc1a Appear Regarding an Unverified Security Certificate in Microsoft Outlook (97/98/2000/2002) and Outlook Express 6? - KB Article - 313688




SSL encryption can cause "0x800ccc1a" error to appear in Microsoft Outlook or Outlook Express.

NOTE: For more information about SSL encryption, please refer to the Wikipedia article on Transport Layer Security.

If Secure Sockets Layer (SSL) encryption is turned on for your email account in Microsoft Outlook or Outlook Express, the following error messages may appear:

  • An unknown error has occurred. Please save any existing work and restart the program. Error Number: 0x800ccc1a
  • The server you are connected to is using a security certificate that could not be verified. A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed field. Do you want to continue using the server?

In some cases, a window appears giving the option to continue. However, this option must be selected each time the program starts and/or while sending or receiving email. To permanently resolve the issue, SSL encryption must be disabled for the email account.

NOTICE: Disabling SSL encryption lowers the security of your email transmission and may allow others to view email communications.
