Remarks

In your Component Object Model (COM) event sinks you can process asynchronous events with the following steps.

1. Obtain the IAsyncNotify Interface from the IExStoreEventInfo Interface that is passed to your Asynchronous sink.
2. Create a new thread to handle the event.
3. Return S_PENDING.
4. Call IAsyncNotify Completed from your new process when you are finished handling the event.

If you return S_PENDING from your event notification and do not call IAsyncNotify Completed, Exchange will notify you of this event again when the store is next restarted.
