There are a few typical reasons for the Pop3 server error and yet, there are simple troubleshooting steps to resolve the problem. Before getting into the solutions, understand the causes of the issue.
So, confirm that the POP3 server address is entered correctly. Make sure whether this issue occurs with the other email clients such as Mozilla Thunderbird or Outlook Express by connecting them to the same POP3 server. Try to configure the firewall/antivirus to let WebMail send/receive messages through POP3/SMTP (25 and 110 ports). To check if the problem has occurred due to Firewall/Antivirus, try to disable the antivirus program temporarily. Then reinstall it and check if the issue is resolved. There are many smart antivirus/firewall programs containing whitelists that include well-known software such as Outlook Express. Due to this reason, this whitelisted software might be allowed to connect to POP3/SMTP servers but not with WebMail. If the issue persists, try to configure the POP3 port.
