If you succeeded in opening an object, the status bar should say the properties came from an object. If not, it'll say they came from the table.The colored bar at the bottom of the dialog says "Properties retrieved from row".
Have you tried just navigating to the Calendar folder? There's more than one way to get to that folder.Ah, that sounds good. Except for the fact that I don't know what the other ways are. You are talking about something that can be done via MFCMAPI, I hope?
