What would be the best way to programmatically determine if Outlook is
installed, and if so, where?

And scanning all available hard drives is not a good option... ;-)

If Outlook is installed, it's path will be
%ProgramFiles%\Microsoft Office\OfficeXX\Outlook.exe
where "XX" is version-specific.
 
And from code the easiest way to see what version is installed and where is
to read the registry key
HKCR\CLSID\{0006F024-0000-0000-C000-000000000046}\LocalServer32.

That string value gives you the full path to Outlook.exe and you can parse
the string to find OFFICE11 (Outlook 2003), OFFICE10 (Outlook 2002), etc.
 
The problem here is that this would not be true if somebody didn't accept the
default location and installed it so some other directory.

Thanks,

Yup, and I know squat about what Ken described, so I should have just kept
my mouth shut.
