  title: Microsoft Teams Provision Channel
  summary: Confirm a team, create a channel in it, and post an opening message.
  description: >-
    A common onboarding pattern when standing up a new collaboration space. The
    workflow first confirms the target team exists, then creates a new channel
    inside it, and finally posts an opening message into the freshly created
    channel. Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
