Allow Sensitive Data Inbound

My Outbound PII DLP policies for Exchange are also blocking users from receiving PII data from External senders.  A Policy Tip in extrernal senders Outlook displays "The following recipients aren't authorized to receive this type of information."

We have 100's of users who receive PII data across all of our business units.  Do I really need to define everyone who will need to receive this data?  Frankly, from an organization perspective, we are not interested who can receive it, just who can send it out.
