Solution

  • If you work with email messages in transport pipeline, you find this information in superior MailItem object. In properties you will find property Microsoft.Exchange.RightsManagement.DecryptionTokenRecipient indicating which user has permission to decrypt the message.

    If you work with EWS look at MailItem and its extended properties (not tested).
