   A proper rule hierarchy is recommended to ensure emails successfully forward to Enterprise DLP.

   • The email transport rule should always be the highest priority rule relative to the other transport rules required for Email DLP.
   • Any email encryption rules not created as part of the Email DLP configuration must be ordered below the transport rules created for Email DLP. Enterprise DLP cannot inspect encrypted emails.
   • There is no impact in regards to priority between the quarantine transport rules, block transport rule, encrypt transport rule, or any other transport rules that exist.
     After Enterprise DLP inspects and returns the email back to Microsoft Exchange, the appropriate transport rule action will occur based on the email header.
