This event occurs when an attachment is being removed from a list item, but no other updates occur. This event occurs after the ItemUpdating(SPItemEventProperties) event if other changes are made to the item.

This event does not occur if the item itself is removed.

Caution noteCaution

When trying to remove an attachment from an item, do not use the property setting Status=CancelNoError to cancel this event, since doing so redirects the user to the "Exception from HRESULT" error page.
