Did you installed SSL certificate on exchange server or are you using auto-discover internally?

Do post the error which you are getting.

Are you trying to configure outlook 2016 or running some test like test-exchangewebservices?

I am trying internally only - not installed any certificate.

Outlook 2016 connects using autodiscover so you need to purchase an SSL certificate with autodiscover SAN name in it and a host A record needs to be added in public DNS.

But I need only to connect internally..It is not working through public DNS..

Outlook 2016 is also working fine now but only making default DNS server to Exchange domain DNS (In my case same Exchange Server).
I tried putting A, CNAME , MX and SRV record for the exchange server but not working.
Actually setup is working fine but after outlook restart it will show error as folders cannot be updated.

I tried deleting all records other than srv but not resolved the issue.
Exchange autodiscovering is working and adding the account but after that it will ask for restart outlook.
But then it will show error for ost as folders cannot be updated.

I resolved it using DNS entries with SRV record as well as A record with new self signed SSL certificate applied including autodiscover.xxx.com

In our case, we found the Autodiscover not working with Fortigate proxy server configuration(needs to put exception) and Symantec also blocking the autodiscovery.
