How to fix the error 0x800CCC19 in Outlook Express and Windows Live Mail
One reason for getting the error code 0x800CCC19 in Outlook Express and Windows Live Mail is a wrong SMTP or POP port number. More specifically, if you have set the outgoing (SMTP) server to work without encryption but you have changed the port number to 465 (the encryption port number), you'll get the above mentioned error code. The whole error message in Outlook Express looks like this:
A time-out occurred while communicating with the server. Account: 'server_name.com', Server: 'server_name.com', Protocol: SMTP, Port: 465, Secure(SSL): No, Error Number: 0x800CCC19
The error message is almost exactly the same in Windows Live Mail.
You'll also get the same error code (0x0800CCC19) if you have set the POP incoming server to use the encryption port number 995 but you haven't enabled encryption from the settings for the email account. The whole error message should like similar to the following:
A time-out occurred while communicating with the server. Account: 'server_name.com', Server: 'server_name.com', Protocol: POP3, Port: 995, Secure(SSL): No, Error Number: 0x800CCC19
The solution is simple: either enable encryption and use the encryption port numbers (465 for SMTP, 995 for POP), or disable encryption and use the non-encryption port numbers (587 for SMTP, 110 for POP). The error code for the same issue with an IMAP incoming server is different: 0x800C006F.
You can check out the tutorial on port numbers for information on the correct port numbers.
You should also check whether the rest of the settings for the email account are correct, e.g. mail server names, SMTP authentication, etc.
Sometimes the scanning of email messages performed by your antivirus application or firewall can cause this error. Check from the options of the antivirus application/firewall whether you can disable the scanning of outgoing and incoming messages. You can also disable or uninstall the application just temporarily until you are sure it's not the cause for the problem.
Sometimes a timeout can also occur when downloading a message with a big file attached or when downloading a message with missing headers.
If you need help with configuring your email client you can also refer to the article or tutorial on the particular email client.
