I have figured out how to hyperlink (html) to an item in my contact
list:

outlook:Contacts/~John Doe

This works great.

Now I would like to be able to issue a command to open a specific
contact from the Global Address List. It is possible that the Global
Address List has some folder name like GAL so that a command like
this:

outlook://GAL/~John Doe

could be issued. Does anyone know how to refer to the Global Address
List by its folder name or to do what I am asking?
