Convertir Exchange Legacy DN

El script convierte todas las cadenas Legacy DN en direcciones de correo electrónico válidas. Para ello, se dispone de un fichero de exportación de la lista global de direcciones, proporcionado por el departamento de TI, en formato .csv y con todos los Exchange Legacy DN y sus correspondientes direcciones de correo. Con estos datos se puede modificar la base de datos para que los Exchange Legacy DN se cambien por direcciones de correo normales.

Ejemplo de CSV:

/o=EMail/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=somefancyname;f.ancy@sample.com
/o=EMail/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=anotherfancyname;an.fancy@othersample.com
/o=EMail/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=m.mueller;m.mueller@mydomain.com
