Common reason of e-mail account login problems or the messages not being received is one of the following:

POP3 user name (UserName property of POP3 object) is different from account name (or from e-mail address).

Some POP3 servers expect user name in form of 'account_name' while others - 'account_name@domain.com'. Sometimes, user name is not related with either account name or e-mail address. Contact your e-mail server administration for details
POP3 mailbox is locked. If someone else is already connected to the mailbox, noone else can establish connection to the same mailbox
POP3 server configuration (domains, MX records, etc.) is incorrect. Check your server's documentation for details

You can exact reason of the problem from MailBee's log file. To enable logging, set EnableLogging and LogFilePath properties of POP3 object.

If the problem persists, don't hesitate to contact our Technical Support Team to get a prompt and helpful reply.

This sample connects to the POP3 server transmitting password as clear text, and then completely retrieves first message in the mailbox (if any). POP3 session log is written into "C:\Temp\pop3_log.txt" file. All possible errors are handled.
