Differentiate between an Outlook appointments

Although Sandeep has a valid point, a situation may exist where an user creates an appointment with boardrooms / recipients and decides to save and then close the appointment without sending it.

I have checked the Item properties of the appointment item and noticed that the following values are only acquired when the send button is clicked:

Name: ConversationIndex - Type: olText
Name: EntryID - Type: olText
Name: GlobalAppointmentID - Type: olText

I think this might be the answer but I am not sure :confused:

Kind regards,

What you're missing is what you're going to run into with methods/events
that overload the same keyword in all managed code. In this case
AppointmentItem doesn't directly expose the Send event since it uses the
same keyword as the Send method.

There are a couple of ways to do what you need to do:

1. Declare at class level an ItemEvents_Event object, say _apptEvents:
private Outlook.ItemEvents_Event _apptEvents;

Then instantiate the event handler so:
_apptEvents = (Outlook.ItemEvents_Event)_appt;
_apptEvents.Send += new Outlook.ItemEvents_SendEventHandler(myHandler);

2. An alternative is to use AppointmentItemClass:
private Outlook.AppointmentItemClass _itemClass; // class level

Then instantiate as follows:
_itemClass = (Outlook.AppointmentItemClass) _appt;
_itemClass.ItemEvents_10_Event_Send += etc.
