I am trying to set up an exchange Server 2019 on Platform server 2019 with an letsencrypt certificate.
Got the host on the same Full qualified hostname “email.4-s.cloud” the same on inside and outside, IPv6 configured and reachable, IPv4 offcourse through NAT only on poort 80 & 443
I am trying to figger out if this https://mediarealm.com.au/articles/lets-encrypt-microsoft-exchange-installation/ procedure is working for me, but can’t seem to figger out what is going wrong?
after setting the hostname in the bindings of the default website in IIS manager i still get the error “No DNS identifiers found” however when i ping on name i get the proper respons as wel in my internal network as on the outside
Can anybody point out to me how to debug the error about the DNS, or even better get me a procedure with letsencrypt for windows server 2019 and exchange service that is complete:)
