Represents information about one instance of an AppointmentItem object which is an exception to a recurring series.
Assembly: Microsoft.Office.Interop.Outlook (in Microsoft.Office.Interop.Outlook.dll)
Unlike most of the other Microsoft Outlook objects, the Exception object is a read-only object. This means that you cannot create an Exception object but, rather, the object is created when a property of an AppointmentItem is altered. For example, if you change the Start property of one AppointmentItem, you have created an Exception in AppointmentItem.RecurrencePattern.Exceptions.
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 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reference, held by another add-in or Outlook, to one of the above objects, your new reference will still point to an out-of-date copy of the object.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.
