I urgently require help with Exchange. <br>I have written a VB Program and using CDO Connecting to Exchange I can send recieve and monitor mail from a web page via ActiveX Dlls but I am unable to add an Appointment Item to the client outlook. I have checked and re checked the code and it is correct. So it appears to be an Exchange issue. <br>The CDO object cannot find the 'CDODefaultFolderCalendar' Folder and thus cannot instantiate the object causing a fail status to be returned. How do I administer Exchange to make this folder visible and accessible to my code?<br><br><br>
