Represents a meeting, a one-time appointment, or a recurring appointment or meeting in the Calendar folder.
Assembly: Microsoft.Office.Interop.Outlook (in Microsoft.Office.Interop.Outlook.dll)
This is a .NET interface derived from a COM coclass that is required by managed code for interoperability with the corresponding COM object. Use this derived interface to access all method, property, and event members of the COM object. However, if a method or event you want to use shares the same name under the same COM object, cast to the corresponding primary interface to call the method, and cast to the latest events interface to connect to the event. Refer to this topic for information about the COM object. For information about the method and property members of the COM object, see _AppointmentItem. For information about the event members of the COM object, see ItemEvents_10_Event.
Use the CreateItem method to create an AppointmentItem object that represents a new appointment.
Use Item (index), where index is the index number of an appointment or a value used to match the default property of an appointment, to return a single AppointmentItem object from a Calendar folder.
When you work with recurring appointment items, you should release any prior references, obtain new references to the recurring appointment item before you access or modify the item, and release these references as soon as you are finished and have saved the changes. This practice applies to the recurring AppointmentItem object, and any Exception or RecurrencePattern object. To release a reference in Visual Basic, set that existing object to Nothing. In C#, explicitly release the memory for that object.
Note that even after you release your reference and attempt to obtain a new reference, if there is still an active reference, held by another add-in or Outlook, to one of the above objects, your new reference will still point to an out-of-date copy of the object. Therefore, it is important that you release your references as soon as you are finished with the recurring appointment.
