How To Fix Error Number 0x800ccc0e?

It's possible your ISP has started to block the standard Outgoing Mail Port (25). You may need to consult your ISP's support pages to get the SMTP e-mail settings.
You can also get error 0x800ccc0e messages when you have anti-virus or firewall software enabled on your pc. Turn the anti-virus or firewall off for a moment and try to send your email again. If it works then the security software is the problem and you will need to contact your ISP for help.
Other Solutions to Windows Errors and Slow PC Performance
Many computer errors are usually caused by corrupt or missing Windows Registry data after removing or installing programs. The Windows Registry is the engine of the Windows operating system. Without it, Windows would not be able to run.
When you install and uninstall software the Windows Registry gets overloaded with "junk" information, which can cause errors and slow down your PC performance.
The best thing you can do, to stop your computer from getting more error messages or further registry corruption, is to repair and clean your Windows Registry.
