More information

This failure occurs because the Exchange 2010 Setup program creates a self-signed x.509 certificate for the server whose FQDN includes an underscore character ( _ ). However, X.509 rules indicate that the underscore character ( _ ) is not valid in X.509 certificate. The setup failure occurs in the Tlscertificateinfo.cs file, which throws the following argument exception:
(Microsoft.Exchange.Net.NetException.InvalidFQDN(name), "subjectAlternativeNames")
This failure occurs because the installation program does not find any valid DNS names in the Subject Alternative Name field of the self-signed x.509 certificate.
