Dopo la migrazione di caselle postali da un server Exchange 2003 ad un server Exchange 2007 alcune caselle potrebbero avere problemi ad accedere via OWA generando l'errore riportato sotto.

Il problema è dovuto ai permessi che non vengono riportati in maniera corretta.
La soluzione più veloce è questa:
1) utilizzare Active Directory Users and Computers;
2) abilitare le funzione Advanced dal menù View;
3) cercare l'utente, cliccare Properties e seleziona re il tab Security;
4) cliccare sul pulsante Advanced;
5) mettere il check su "Inherit permissions from parent";
6) cliccare due volte OK
