If possible why not use rules? https://support.office.com/en-us/article/Manage-email-messages-by-using-rules-50307363-0e79-4f6a-95c0-04b922a2ff13?ui=en-US&rs=en-001&ad=US — Paul Zahra, Jan 19 '15 at 09:21

OpenPop implements the POP3 protocol. This protocol is old, and does not know about such things as folders. Therefore, the OpenPop implementation cannot handle folders as well.

If you need to use folders, consider using some IMAP client instead. IMAP is a newer and more modern protocol.

As J. Steen has pointed out. No, you can't with OpenPop.

Just encase you still want to do it and it wasn't a purely academic question. Taken from MSDN
