Working with Asynchronous Events

Topic Last Modified: 2006-06-12

The following information is important when working with asynchronous events:

  • Moving a folder does not cause an event to fire on any items in the folder.
  • Copying a folder causes an event to fire on all items in the folder.
  • Deleting a folder does not cause an event to fire on items (messages and documents) in the folder. However, it causes an event to fire on each of the subfolders.
  • An asynchronous event does not have any firing priority.
  • Asynchronous events are not processed in any specified or guaranteed order. The event source does not wait for asynchronous events to finish.
  • When the OnDelete Method event is called, the item has already been deleted.
  • There is no guarantee as to how soon asynchronous event notifications are called after the event occurs.
  • An asynchronous event is not processed if a synchronous event aborts the asynchronous event.

Note

E-mail messages processed in event sinks must be compliant with RFC 822. They also must end with a carriage return/line feed (CR/LF).
