Outlook 2007 doe snot allow you to edit teh message body on a post form
without clicking on Other options | Revised contents. (Revised contents
deletes the original and create a new item from teh previous item)

You can edit the message body on a contact form, a task form and an
appointment form. The email form you can choose Other Options | Edit message.

Does anyone know why the post form is singled out? Is there a registry key
or code that can be used to override this behaviour?

Thanks,
