    For all those who wonder what kind of information is found by this script: It shows information contained in the SecurityDescriptor msExchMailboxSecurityDescriptor of an LDAP object, which does not necessarily match the "real" mailbox settings as the LDAP information is not updated if the real mailbox settings are changed.
