Créer la liste des adresses emails définies dans Exchange 2007/2010 en PowerShell (24.05.12)
Il n'existe pas d'endroit dans Exchange où trouver la liste de toutes les adresses emails. Voici un script qui permet de tirer cette liste automatiquement. Attention! Les dossiers publics activés avec une adresse emails ne sont pas inclus dans la liste.
