Mail Error – 0×800ccc91
Symptom
There was a problem logging onto your mail server.
Your UserName was rejected. Account: ‘mail.yourdomainname.com’, Server: ‘pop3.norton.antivirus’, Protocol: POP3, Server Response: ‘-ERR’, Port: 110, Secure(SSL): No, Server Error: 0×800CCC90
Error Number: 0×800CCC91
Solution
This error message is caused by the fact that you have set an anti virus program, in this case Norton AntiVirus, to scan all emails automatically.
Changing the settings within Outlook Express will not solve this issue. You need to go to Norton and change the settings there.
