Outlook parameters problem when using ACFEXECUTE element

Hello,

I want to initiate a prefilled email by using the ACFEXECUTE element on a 7.02 system. After the challenges to configure the whitelist etc.. I manage to start outlook successfully - using this:

lv_application = 'C:\\Program Files\Microsoft Office\Office14\Outlook.exe'.

lv_argument = '/c ipm.note' .  

wd_this->set_execute_method( application = lv_application                              

                                               argument    = lv_argument ).

BUT - when outlook is started it displaying an error popup saying "Invalid command line arguments". Is there someone who might give me a hint how the parameters / argument should be passed? Using Outlook.exe /c ipm.note works fine from the commandline.

Thanks you for a hint.
