Add company logo to email form and other customizations

[fazder]

I'm trying to customize Outlook's standard mail form to include our
company logo at the top of the message field as well as an additional
image at the bottom of the message field. We would also like to have
the cursor default to a position between the images, and have the
user's signature automatically insert at a specific location. Is any or
all of this possible? Can anybody point me in the right direction for
guidance on how to accomplish these things?

Thanks for your help!
