  title: Microsoft Office 365 Update Draft and Send
  summary: Create a draft, patch its subject and body, then send the updated message.
  description: >-
    Refines a draft before sending it. The workflow creates an initial draft
    message, patches the draft to update its subject and body (the update returns
    200 with the revised message), and then sends a message carrying the updated
    content. Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
