  title: Microsoft Office Escalate an Inbox Message to a Teams Channel
  summary: Match an inbox message against a filter, read it in full, and raise it as a Teams channel alert.
  description: >-
    A cross-service flow of the kind the unified Microsoft Graph surface exists
    to enable: Outlook and Teams reached with one token in one sequence. The
    workflow selects inbox messages with an OData filter, ends quietly when
    nothing matches, reads the top match in full, and posts the sender, subject,
    and preview into a Teams channel so a shared-mailbox alert reaches the
    people who act on it. Every step spells out its request inline so the flow
    can be read and executed without opening the underlying OpenAPI description.
