Issues with integration of exchange on-prem to Teams
Hi masterog-305,
it seems the issue lies in how your network routes traffic. The curl outputs indicate requests from outside are directed to internal instead of external IP/DNS.
Check:DNS Settings: Ensure that your DNS settings are correctly configured to route traffic to the correct IP addresses.
Firewall/Proxy Settings: Check your firewall or proxy settings to ensure that they are not blocking or rerouting traffic incorrectly.
SSL/TLS Configuration: From the curl output, it seems like the SSL/TLS handshake is successful, but itโs worth checking if there are any issues with the SSL/TLS configuration that could be causing problems.
Autodiscover Configuration: The error message from the analyzer suggests that there might be an issue with the Autodiscover configuration. Ensure that the Autodiscover service is correctly configured and that it can be accessed from both inside and outside your network.
Network Routing: Check your network routing settings to ensure that traffic is being correctly routed from the outside to the inside.

As you suggested and we expected it was a nat rule typo that caused all this. It was an external party that made the error and they told us everything was allright on their side.
Glad that it works now and thanks for the time and help ๐
