You could set an Outlook Application object and if it works Outlook is
installed. You can also look for Outlook.exe in the file system or read the
registry to see where Outlook is installed if at all.
HKLM\Software\Microsoft\Windows\CurrentVersion\App Paths\OUTLOOK.EXE is the
location where the Outlook.exe path is listed if it's installed.
