  title: Microsoft Outlook Review Folder and Mark Read
  summary: Open a mail folder, list its unread messages, and mark the top one as read.
  description: >-
    An inbox-cleanup pattern. The workflow reads a well-known mail folder such
    as inbox to confirm its unread count, lists the unread messages inside it,
    and marks the most recent unread message as read by patching its isRead
    property. The folder id and message id chain across the steps so the flow
    runs without opening the underlying OpenAPI description.
