When you have a contact open and click the "Map to address" button the
redirector has been broken and you end up on the Microsoft Update Page. The
link can be cahnged to point to wherever you want it to. It does require
that you make a change to your registry.

Here is the registry String key that needs to be added:

Click the Start button on your desktop
Select RUN...
Open REGEDIT
Navigate to:
[HKEY_CURRENT_USER\Software\Microsoft\Office\9.0\Outlook\Options\General]
Click EDIT on the menu
Select NEW from the menu
Then STRING VALUE and name it MapScriptURL

Then depending on where you like to get your maps from make the value as
follows, (Just copy and past the value that is shown below next to the place
you wish to get your maps from):

For MapQuest:
Give it a value of :
www.mapquest.com/maps/map.adp?address=<0s>&city=<1s>&state=<2s>&zip=<3s>

For Yahoo:
http://maps.yahoo.com/maps?newFL=&addr=<0s>&csz=<1s>+<2s>+<3s>&srchtype=a&getmap
=Get+Map

For MapPoint:
http://mappoint.msn.com/home.aspx?strt1=<0s>&city1=<1s>&stnm1=<2s>&zipc1=<3s>&sr
c=OL&o1=<0s>&o2=<1s>&o3=<2>&o4=<3s>&o5=<4s>

The icon that takes you to the map of the address no
longer works.  It takes me to the microsoft home page
instead of the mapquest site of the address in the
contact.  How do I change it back?
