Hi, I have a single Exchange Server 2013 that is setup to receive emails from the internet and local. Im receiving error message that my certificate is not matching with my FQDN. When I try to change my FQDN that can match with my Certificate common name, I receive a message that I need to disable Exchange Server Authentication method that I can be able to change it. So, I disabled this option and then I stopped to receive the message error. However, I stopped to receive email. I notice that when Exchange Server Authentication method is unchecked, Im not able to receive emails. Once I checked it back and change back my FQDN, I started to receive emails. Why do I need to have Exchange Server Authentication method if I only have a single server? How is it possible to fix this problem?
Thank everyone!
Microsoft Exchange could not find a certificate that contains the domain name server.mydomain.local in the personal store on the local computer. Therefore, it is unable to support the STARTTLS SMTP verb for the connector Default servername with a FQDN parameter of server.mydomain.loca. If the connector's FQDN is not specified, the computer's FQDN is used. Verify the connector configuration and the installed certificates to make sure that there is a certificate with a domain name for that FQDN. If this certificate exists, run Enable-ExchangeCertificate -Services SMTP to make sure that the Microsoft Exchange Transport service has access to the certificate key
