You need to have a Public Certificate for example edge.domain.tld with a private Key installed on your Exchange Edge Server.
Get-SendConnector -Identity YourInternetConnectorName | fl
#Check the Property TlsCertificateName
#Create the Variable on your Edge Server
$Cert = Get-ExchangeCertificate -Thumbprint "ThumbPrintOfEdgeCertificate"
$tlscertificatename = "<i>$($cert.Issuer)<s>$($cert.Subject)"

Set-Sendconnecter -Identity "ValueFrom $tlscertificatename" -TlsCertificate $tlscertificatename
