  title: Microsoft Exchange Prepare and Send a Forward
  summary: Create a forward draft, edit its body, and send it to new recipients.
  description: >-
    A controlled forwarding pattern on Microsoft Graph mail. Rather than
    forwarding in a single shot, the workflow creates a forward draft from an
    existing message, updates the draft body to add context, and then sends the
    finished forward. Each step inlines its request so the flow can be executed
    without consulting the underlying OpenAPI description.
