I found this code online. It allows a user to see their current meetings in their Outlook Calendar. The only two requirements is that the user has IE and Outlook on their machine.

<object classid=”clsid:0006F063-0000-0000-C000-000000000046″
id=”ViewCtlFolder”
width=”100%”
height=”400px”
codetype= “application/x-oleobject”
codebase=”http://activex.microsoft.com/activex/controls/office/outlctlx.CAB#ver=9,0,0,3203″>

<param name=”Namespace” value=”MAPI”>
<param name=”Folder” value=”Calendar”>
<param name=”Restriction” value=”">
<param name=”DeferUpdate” value=”0″>

</object>
