The Appointment class has a BusyStatus property. This is fine for checking the busy status of a particular appointment. However, is there a way to query the calendar for the busy status of a particular time slot? For example, is there a way to query the calendar to see if 10-11am is free?

Accessing this property either using app.Properties[AppointmentProperty.MeetingOrganizerName] or app.MeetingOrganizerName throws an exception of type 'System.Runtime.InteropServices.COMException' RESULT of 0x80070006. I think this is the COM Error code for invalid handle. Other Appointment functions...

I give up. I've tried using the windowsmobile.pocketoutlook to create an appointment, (just a basic "Meeting 8:00" appointment) but am having no luck. Can someone please post a VB.NET code snippet that shows how to do it? Thanks!
