Delete Error Messages in Outlook Express

The "Server Error: 421" error message appears in Outlook Express when you are on a server that is utilizing a POP3 connection and you attempt to send out an email to another account using the POP3 connection. The error message appears because the number of connections on the server is set too low. The number of connections needs to be set higher for the error and its messages to disappear. " Error 0X800ccc90" or "Error 0x800ccc18" is an error in which the Outlook Express program mistakenly stops your password from being authenticated, thus preventing you from logging into Outlook Express. This error can be fixed from within the Outlook Express program.
