How to set Outlook Properties

[Jefree]

I'm trying to set the following properties in Outlook from Access with VBA:
1. Mail Format - I need to set this to HTML
2. StationeryPicker - I would ideally like to create a new Stationery from an htm file on our network and apply. If this is not feasible, I would like to be able to select a Stationery from the list of stored available.

Thanks in advance to anyone who can help me!
