the servers are gone from the servers ou under adsi edit admin group
no one server crashed as below is visible but still failing

Error:
The following error was generated when "$error.Clear();
if ($server -eq $null)
{
new-exchangeserver -DomainController $RoleDomainController -Name $RoleNetBIOSName
}
" was run: "Microsoft.Exchange.Data.Directory.SystemConfiguration.DefaultAdministrativeGroupNotFoundException: Could not find the default Administrative Group 'Exchange Administrative Group (FYDIBOHF23SPDLT)'.

Answer 1

thank you all i ended up creating a windows powershell shortcut with exchange snapin pre mounted on it

a workaround but it works

%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe -NoExit Add-PSSnapin Microsoft.Exchange.Management.PowerShell.SnapIn%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe -NoExit Add-PSSnapin Microsoft.Exchange.Management.PowerShell.SnapIn

Answer 2

Hi,

Did you run the below commands using the Exchange 2019 setup file before the installation? If not, please prepare the Active directory before the installation

setup.com /PrepareSchema /IAcceptExchangeServerLicenseTerms

setup.com /PrepareAD /IAcceptExchangeServerLicenseTerms

For Coexistence, Exchange 2013 Cumulative Update 21 (CU21) or later is required on all Exchange 2013 servers in the organization, including Edge Transport servers.

Hi,
the servers are gone from the servers ou under adsi edit admin group
Do you mean you uninstalled the servers by removing them from ADSI edit? It’s not supported and may cause problems.

Have you run /prepareAD before install?
Please run the command and see if the problem persists. Make sure your account is a member of the Enterprise Admins security group.
If you see any error code, post the detailed information in text or by screenshot.

Answer 5

So, prepareSchema and PrepareAD ran without any issues and the error was thrown only during the setup. Also, now the exchange 2019 has been installed but unable to connect the powershell. Please correct me if i misunderstood.

For the powershell error, try adding the exchange server object to the "Exchange Trusted subsystem" if its not already present and the logged on/administrator account to the "Organization management" group and check again
