WARNING: When an item can't be read from the source location or can't be written to the target location, it will be
considered corrupted. By specifying a non-zero BadItemLimit, you're requesting that Exchange not copy such items to the
 target location. When the request is complete, such corrupted items won't be available at the target. When the source
is deleted, these items will be completely lost.
