Answer 1

It seems like you have might be an issue with the domain name you're using in the command. Here are some things you can try to fix the issue:

1. Verify the domain name you entered in the command to make sure it's correct and matches your actual domain name.
2. Make sure your server can connect to the domain controller and that the DNS settings are correct.
3. Before installation, make sure that all the necessary prerequisites for Exchange 2019 are installed on the server (like the Windows features and roles).

Let me know if you have any query.

Hi @Mortaza Ali ,

Welcome to the Microsoft Q&A platform!

First of all, make sure you meet all the prerequisites for installing exchange server, which you can refer to:https://learn.microsoft.com/en-us/exchange/plan-and-deploy/prerequisites?view=exchserver-2019#exchange-2019-prerequisites-for-preparing-active-directory

Based on the error message you provided, it seems that the domain name is invalid. Please check if the “Domain Name” field is the same as Sever Manager. You can check it by clicking on local server.

However, you can also troubleshoot the issue from the following ways:

1. Granting Schema Admin and Enterprise Admin permissions to the current user in ADUC.
   Open ADUC by DC, check the user you need to install and click member of to add the above permissions to it.
   
2. Run
   Setup.exe /IAcceptExchangeServerLicenseTerms /PrepareSchema Setup.exe /IAcceptExchangeServerLicenseTerms /PrepareAD Setup.exe /IAcceptExchangeServerLicenseTerms /PrepareAllDomains

3.Check the detailed installation logs. CD:/ExchangeSetupLogs/ExchangeSetup.
Find the log truncation and troubleshoot further based on the information it provides.
