We are looking to use a Zixcorp solution in the future for external emails, but I'm wondering if this interim solution is possible and if so how.
Can Outlook 2013/Exchange 2010 be configured that when an email is sent to someone within the local domain it is sent normally, but when it is to any other domain a prompt comes up stating something like "Does this email contain PHI?" or "Are you sure you want to send this email?". Then the user could click YES or NO and either the email would be sent or not based on the response.
We would only want this to occur for external emails, not internal emails.
