  -SmartHosts $smtpEndpoint `
  -TlsSettings DomainValidation `
  -TlsDomain $smtpEndpoint `
  -CloudServicesMailEnabled $true `
  -IsTransportRuleScoped $true

Note: The -IsTransportRuleScoped $true parameter is the PowerShell equivalent of the Web UI's "Only when I have a transport rule set up that redirects messages to this connector" option. No mail will flow through this connector until a transport rule is configured.
