Quick connect to company's POP 3 is failing

0 votes

I am using my username and password that currently has mail and I can access via outlook. It errors with message bad user or password. How can I track the issue since I am using a valid name and password?

Thanks

Limilabs.Mail.Log = true;

using(Pop3 pop3 = new Pop3())
{       
    pop3.Connect("mail.mycompany.com"); 
    pop3.UseBestLogin(
        "userMe@mycompany.com", 
        "!user-me_Password#");

    foreach (string uid in pop3.GetAll())
    {
        IMail email = new MailBuilder()
            .CreateFromEml(pop3.GetMessageByUID(uid));

        Console.WriteLine(email.Subject);

        // save all attachments to disk
        foreach(MimeData mime in email.Attachments)
        {
            mime.Save(mime.SafeFileName);
        }
    }
    pop3.Close();
}

"Logon failure: unknown user name or bad password." is the error returned by the server. It is not accepting your credentials.

Please double check for spelling mistakes.

Make sure POP3 protocol is turned on for your account. Please ask your email server administrator for server, port, and if SSL/TLS should be used.
