Of all the email clients that we use today, MS Outlook is quite familiar among most of us. MS Outlook was first released in 1997 and since then it has become very popular. There are many other email clients that have been first released since a long time ago and are still being used today, but MS Outlook’s popularity and use has been ever increasing since its first release. This is mainly because of the user-friendly and interactive GUI, versatility, and loads of features that MS Outlook provides. But just like many other applications, MS Outlook is prone to certain errors that may arise due to a number of reasons. In this article, we are specifically going to discuss the error 0x800ccc1a and learn how to fix the error 0x800ccc1a in Microsoft Outlook.

Reason for the error 0x800ccc1a

The Outlook error 0x800ccc1a can manifest itself with error messages like:

An unknown error has occurred. Please save any existing work and restart the program. (Account: ‘xxx‘, POP3 Server: ‘xxx.xxx.xxx‘), Error Number: 0x800ccc1a

An unknown error has occurred. Please save any existing work and restart the program. (Account: ‘xxx‘, SMTP Server: ‘‘), Error Number: 0x800ccc1a

These error messages generally present themselves when there is error pertaining to SSL (Secure Sockets Layer) encryption. Such kind of error arises when the wrong port number is specified on SMTP or POP3 servers. Since this error causes the problem with SMTP and POP3 servers, hence this error presents itself with a common SEND/RECEIVE error.

Reason for error 0x800ccc1a is not limited to SSL port number incompatibility, but can also be caused in case of Outlook PST file error issues, Improper MS Outlook installation, etc. Now that we know the reason for the error, let us discuss the ways to fix the error 0x800ccc1a in
