Outlook open calendar with specific persons calendars

[Aliensite]

I want to open the Outlook calendar on a users computer from a webpage where the calendar have marked and shows other users calendars. Who these "other users" are should somehow be defined from the webpage. I know that i can open the Outlook calendar with this: \[code\]<outlook:calendar>\[/code\]. My hopes was that i somehow could pass in which usercalendars should be visible, when Outlook opens, in that string, but a lot of google searching didn't help me. Is this even possible?This is for a intranet system, so i know that the user have Outlook installed.
