We have a shared public folder which contains about 6,000 contacts. What I would like to do is to setup three access groups for this folder:
Group A Read only access to all contact records but NO access (read or write) to the Notes: field of each contact record.
Group B Read only access to all contact records WITH read only access to the Notes: field of each contact record.
Group C Read & Write access to all contact records including the notes field.
I know we can do Group B & C quite simply. Is Group A possible? If so, how do I set permissions on a specific contact record field for both existing & new contacts in Exchange 2007?
