How to change Outlook’s “Map It” to Google (and to customize to display driving directions).
For Office 2010, the regisrty path: HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Options\General
I had to add a registery key “General” under “Options”. Then add a “String Value” type key under “General” with the name “MapScriptURL“.
For just the map, use the value:
http://maps.google.com/?q=<0s>, <1s>, <2s>, <3s>, <4s>
If you want a start and endpoint (driving directions), use the value:
http://maps.google.com/?saddr=street,city,state,zip,country&daddr=<0s>, <1s>, <2s>, <3s>, <4s>
Caution, the registry is a tricky area to workin and potentially can mess things up in your computer quickly. We assume no risk with this advice. We can perfrom this service for you remotely.
