Create secure eEnvelopes

When adding security to a document, you can choose to encrypt only the attachments. The PDF document in which documents are embedded is called an eEnvelope. Encrypting only the document attachments is especially useful for sending secure file attachments without modifying the file attachments themselves.

Choose Document > Secure > Secure PDF Delivery, follow the on-screen instructions to select PDF files, choose an eEnvelope template, and select a delivery method.
