I was trying to use some command line switches when starting Outlook
to create a new message and I received an error when combining a few
switches.

Well, either Outlook has it wrong or the web site I referenced has it wrong.
Outlook does not recognize the "?&xxx" mailto extensions. If you leave off
the "&", then they work. For example, the web site shows:

MailTo with message already started in Body
a ?&body=I am having trouble finding
information on "

Outlook will obey it if you write it as:

a ?body=I am having trouble finding information
on"
