I have the following problem (Outlook 2003) when double-clicking on a .vcf attachement:

user received an email with business cards in attachment:
1. saving the vcf files & importing them into Outlook contacts works fine.
2. when double-clicking on vcf file as attachment in a mail -> open with -
outlook.exe -> an error message appears:

Error: The command line argument is not valid. Verifiy the switch you are using.


Has anybody ever encountered this? Forwarding the mail to another user on another computer, does not recreate this problem.
