after i try to Enable-ExchangeCertificate i get this msg.
WARNING: This certificate will not be used for external TLS connections with an FQDN of 'IL-CAS1.ABC.local' because the
CA-signed certificate with thumbprint 'E48EA0B3FE66DF65630E132E2D6EC9BB9FC6877E' takes precedence. The following
receive/send connectors match that FQDN: Default IL-CAS1, Client IL-CAS1, Relay.
From what I understand I should just delete the old thumbprint
