Generate Outlook Calendar

I am wanting to generate an Outlook calendar webpage from my server via a button or link on my webpage.  Since the calendar changes from hour to hour (new appointments added), I want it generated anytime the button is pressed.  I'm familiar with turning the Outlook calendar into a webpage by going into Outlook itself, but I want this done all on the Internet. 

Can anyone guide me in the right direction?  I've done searches on google, but can't find anything good.  Any help would be appreciated.

Thanks in advance!
