Outlook 2010 shared calendar

[svp46]

Hi all,

I want to share a calendar with a few people but i also has to be visible in all of these people's To-do bar. (outlook 2010)

Now when i share this shared calendar or when i tried to share separate occurring appointments they are not visible in those peoples to-do bar and not in mine.

So how can i create a shared calendar (with a few occurring appointments) and all of us can see this in there to-do bar?
I searched on some forums, google, outlook help,...

Thanks!
