A time-out occurred while communicating with the server. Account: 'pop3.nethere.net', Server: 'pop3.nethere.net', Protocol: POP3, Port: 110, Secure(SSL): No, Error Number: 0x800CCC19
1. This is a possible corruption of the pop3uidl file. Close your internet connection and all programs. Search for the file pop3uidl and delete it. Reconnect and it should work.
2. Repeat step 1 with a reboot before you check your mail again.
3. You may have a corrupt or a very large file attachment on the mailserver. Large file attachments, mail that are missing headers, or mail that do not conform to the mail RFC's can cause this.
4. Access your email via webmail, and download the messages one by one to narrow the problem down. If you have a large file that is too big to download, contact the sender and have them break up the message into a few smaller ones.
