From the developer:
Using ADO it is now again possible to administrate all important attributes of an Active Directory-Object, including the Exchange 2010 or 2007 attributes, with one tool. ADO also allows the administrator to manage exchange mailboxrights as done in Exchange 2003. ADO displays the Active Directory objects in the directory hierarchy, like the ADUC, or in a flat Browser structure, like the global addresslist in Outlook.
