I just finished setting up and implementing a new Exchange 2013 server. It was a migration from SBS 2008. Email works beautifully along with
activesync and outlook anywhere. The only problem I'm having is TLS will not work on the Internet facing receive connector and I cannot figure out why. I use the AD CA to sign certificates and then distribute the root certificate to computers outside
the domain. The CA was migrated from SBS to a new DC with a different hostname, but I kept the CA name the same. I can issue new certificates without error, and the CRL distribution points appear to be working. I have confirmed the desired
certificate is assigned to SMTP, and that the receive connector is set to use TLS. Where can I look to figure out why Exchange is not offering TLS?
