  title: Microsoft Office 365 Draft and Send Mail
  summary: Create a draft message, read it back, then send it from the mailbox.
  description: >-
    A review-then-send mail flow against the signed-in user's mailbox. The
    workflow creates a draft message in the Drafts folder, reads the draft back
    to confirm its content, and then sends an equivalent message via the sendMail
    action. The sendMail action returns 202 Accepted because delivery is
    asynchronous. Every step spells out its request inline so the flow can be
    read and executed without opening the underlying OpenAPI description.
