It seems to have something to do with this key
CODE
[HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Setup]
"First-Run"=hex:34,1b,87,8b,a8,68,02,47,ac,d1,be,08,72,c8,60,ef
If you delete the key it recreates the link on program startup, trouble is the key seems to change with every install, I have uninstalled it 3 times and each time imported the previous values but a shortcut has still been created and the hex value has changed, could be related to time of install
