Mail inbox

I have three email accounts (pop) and messages display in the inbox as well as in the appropriate folders. I wish to delete messages from inbox but leave them in appropriate account inbox. If I delete the messages from inbox or named folders, they all disappear when i really just want the 'inbox' clean

Can i not move message to designated folder and have it not showing in inbox?

example:

Inbox (keep clean)

Office (3)
Copy (12)
John (33)
