For delegates or shared mailbox members, when they have full access of the owner's mailbox but are not allowed to read encrypted email, Outlook will have a new cmdlet setting to block the owner's protected email access which covers ad-hoc encrypted email as well as email with protected MIP sensitivity labels.
