Hi,

I am having problem to access the pop3 at the exchange server in my company remote site using a simple program written in C#. However, I am able to access it through MS Outlook. My program is working fine when I tested it on a gmail account. I was able to get to the "Pop3MailClient Connection State Authorization" but in the end i was getting this message from the pop3 server '-ERR Logon failure: unknown user name or bad password.'. I am sure that my userid and password are correct. Can anyone help me on this please....

BTW, the pop3 authentication set in the exchange server is "basic authentication" and "Simple Authentication and Security Layer".

Just check your User name and Password in the server to make sure it is the same. All it takes is just a simple error such as a CAPITAL letter missing or a letter/number not being included in either the User name or Password.

Please post back if you have any more problems or questions.
If this information is useful, please mark as helpful. Thanks.

It may require the fully qualified U/N such as something like 'myusername@mydomain.com' instead of the simple U/N of 'myusername'. If you're already using the fully qualified U/N, then shorten to just the simple U/N. POP3 and Exchange logins are different.

Thanks a lot guys. Now I can finally log on to the pop3 server. It seems like the username is just a simple username instead of username@domain.com.
