Problema con exchange server en la red local

Question

Buenos días, he configurado un servidor exchange 2019 de pruebas y tengo el siguiente problema:

Si configuro Outlook desde dentro del servidor se conecta al buzón perfectamente

Si configuro Outlook desde un ordenador de la red local no hay manera que se conecte al buzon.

el dominio es xxxx.local

Hi @Jordi Font Nebot ,

Thank you for the information.

According your screenshot, I suppose the main cause is a record named autodiscover missing from the DNS.
You could add an autodiscover record in DNS to point to the ip address of exchange and see if it works.

If it still does not work for you, please have a check which version of the outlook in your local computer. If it is Outlook 2016 version 16.0.6741.2017 and higher ,it is suggest that add a DWORD(32-bit) called ExcludeExplicitO365Endpoint to the registry of the local computer .

Please refer to the following steps:

1. Open the registry.exe of your local computer , enter the following address:

HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\AutoDiscover

(NOTES:

1. If there is not a KEY named Autodiscover, please add it at first.
2. Be careful when modifying the Registry since any changes could potentially cause your computer to not work properly.
   )

2.Right click and create a new DWORD(32-bit) called ExcludeExplicitO365Endpoint and set its value data to 1.

3.Create a new profile for your account in the control panel.

Answer 2

The problem was fixed
I had to put the server ip as the primary DNS
I had to create the dns entry autodiscover
Now it's perfect

Thank you so much!
