Folders pop up on desktop from outlook 5

After installing 98 second edition and using outlook 5, for each folder I use, the folder is placed own my desktop. If I delete mail the delete folder icon is own my desktop, the same for each folder I use. Sent,drafts,personal folders and so on. IfI right click and use properties I see the archive box checked, I then can mark hidden and refresh the screen and they are gone. The next time I use them they return. Help me get rid of them……
