Hi Justing
1) This is correct, as only the stubs were deleted, and not the content in the archive.
2) It is possible, yes. Are you able to find a common pattern as to why? If you would delete the content of the archive after the restore, EV *should* take care of the shortcuts, because they are then orphaned
3) E-Mails are restored to their "Original Location", if you haven't enabled the moved shortcut tracking in EV8. (not available before EV8)
