I am looking for a way to automatically sync a copy of an appointment/meeting from a private calendar within a user's mailbox to a public calendar for my entire agency. We have been using Add2Exchange for some time with mixed success. Does anyone know if the newer versions of Exchange (2007/2010) support this functionality natively? We are currently using Exchange 2003 Ent on Server 2003 Ent. Also, if Exchange 2007/2010 won't do it natively, how about Sharepoint? Other third party software? Custom code/scripts?
