  title: Microsoft Office 365 Notify New User
  summary: Create a user, then send a welcome email to their new mailbox address.
  description: >-
    A cross-resource onboarding flow spanning the Users and Mail resources. The
    workflow creates a new user, reads the user back to capture the resolved
    userPrincipalName, and then sends a welcome email addressed to that user from
    the signed-in account. The create returns 201 and the sendMail action returns
    202 Accepted. Every step spells out its request inline so the flow can be read
    and executed without opening the underlying OpenAPI description.
