That error usually means that some folder corruption in the message store
has taken place. Close Outlook Express and then find the hidden file
"folders.dbx" and delete it. Then reopen Outlook Express.

I get an unknown error message when trying to send email. It is as follows:
"An unknown error has occurred.Protocol:SMPT, Port:0, Secure(SSL):
No,Error
Number 0x800C012E." I've contacted my server and my settings are correct

they seem to think there is a problem with the outlook program. Help?? I

able to send and receive using Microsoft Outlook, so I cannot figure out
what's wrong!
