Error 0x800CCC18 - Logon attempt failed
If you receive Error 0x800CCC18 SICILY_LOGON_FAILED, this means that your logon attempt has failed. Outlook Express will return an error similar to the following:
"Unable to logon to the server using Distributed Password Authentication.
Account:'Company POP3 Server Accnt.',
Server Response: '-ERR The AUTH protocol exchange was cancelled by the client.',Port: 110, Secure(SSL): NO, Server
Error: 0x800ccc90, Error Number: 0x800ccc18"
A common cause for this error is where you have asked Outlook Express to log on using Secure Password Authentication.
As BT Business does not require you to use Secure Password Authentication, please ensure that this option is NOT selected within your mail account properties.
