Can you provide more details please on what you're doing and what you hope to accomplish ?IPM.Note is not a custom form. It's the standard form for messages. And running a published custom form isn't going to "change the icon" on any existing items. Furthermore, the way to "run" a published custom form is with the Tools | Forms | Choose Form command. Messages created that way should show your custom icon, assuming it's the right size and color depth, like the standard icons.
