I have a classic setup. Kemp Loadmaster and two Exchange 2016 server CU7. I used the Exchange 2016 Core Template "Exchange 2016 https - Reencrypted" Now I have the following situation. When I set up the virtual IP i checked first of all the OWA connection. This works like a charm, but when I start outlook, it tries to connect but unfortunately without success. Services are all up. So where is the error. What did I wrong. Any suggestions?
If the health checks are showing green, and OWA works but Outlook doesn't
most commonly the issue is with ciphers suite or if the Outlook client (depending on the version) is using older security such as SSL 3.0 or TLS 1.0
can you check the Microsoft Remote Connection Analyzer https://testconnectivity.microsoft.com/
this will give you more details to what failed,
