If a HTML page is set as a folder's home page, is there a way to detect that
it is being viewed via Outlook and then access the Outlook object model via
code in the page?

Now that the folder home page featuring the Outlook View Control is up and
running, I'm looking at giving my users a means to setup various options. I
can now programmically switch the folder home page from the OVC page to one
that will displays the setup options. However, to switch back I need access
to the Outlook OM in order to change the folder home page back. Right now,
I've got a OVC on the setup page with it hidden (style="display:none;")
