Helping people with computers... one answer at a time.

Error Number 0x800CCC19 is a timeout, which can be caused by many things. Most common appears to be interference by your anti-virus program.

How do I resolve the error message "Error Number: 0x800CCC19" when sending a message in Outlook Express in Microsoft Windows XP?

This is one of those times when Google really is your friend. A search on just the error number 0x800CCC19 returns lots and lots of relevant items.

And most seem to center on one particular cause.

At the top of the results list (at least when I looked) was a Microsoft Knowledgebase article: Error message when you view a POP3 e-mail account with antivirus software installed: The operation timed out waiting for a response from the receiving (POP) server 0x8004210a. It's not a particularly helpful article, stating on that this error has been seen when some anti-virus packages are used to scan email. It then points you at the various anti-virus vendors for more information.

The common thread among all the anti-virus related reports is simple: your anti-virus program is interfering with the upload, or download, of email as it attempts to perform a virus scan on the messages being transmitted. In the configuration of your anti-virus program, turn off the "real time" or active scanning of email being sent or received - if the problem goes away, you now know the cause.

"The common thread among all the anti-virus related reports is simple: your anti-virus program is interfering ...

If that was the cause the next thing to do is, as the MS article indicated, check with the manufacturer of that anti-virus program for a possible fix. It could be as simple as a setting, or it could require an upgrade to a newer version of the anti-virus scanner. Or they may not have a solution, and you'll have to leave the real time scanning of email turned off, or switch to a different anti-virus solution.

Whether or not to leave real-time virus scanning turned on for your email is a personal decision. If you, and everyone that uses your computer, is good at identifying suspicious email, and not opening unknown attachments, then it's quite possible you don't need it. On the other hand, if you're not sure it's a nice feature to leave enabled for that additional security.

In the Google results on 0x800CCC19 there's also a report of corruption in the "pop3uidl.dbx" file. The solution presented is to exit Outlook Express, delete that file, and then restart OE. I'm always nervous just deleting potentially important files, so my recommendation is that rather than deleting it, you rename it. That way if you need it back for any reason, you still have it.

I've had this 0x800CCC19 timeout error for Years, especially when sending Large messages with multiple recipients (3 different anti-virus, with outgoing scan disabled)?-
XP then Win 7- Outlook Express, and now Windows Live Mail.

Leo was right with me (thanks!)! Solution-
I let my anti-virus scan the incoming message, then "Fully Exit Before" i Send.
Try it!

@Rick
It is normally located here:

c:\Documents and Settings\{user name}\Local Settings\Application Data\Identities\{a very long obscure name with letters numbers and dashes}\Microsoft\Outlook Express\
