fallo en scanpst

buenas tardes.
tengo un archivo pst que ha llegado al límite de dos gigas y me dice outlook
que le pase la herramienta reparar bandeja de entrada.
supongo que esto es el scanpst.
pues bien,
lo paso y al final de la fase 4 me dice que se produjo un error.
este es el log que genera:
