We installed and uninstalled exchange2010.
We are trying to install a new exchange server but still have this error:

Hello Dear,

Have run all these commands before starting installation?

Setup.com /ps

Setup.com /preparedomain

Setup.com /preparead

I would suggest to run all the above commands and start the installation or you can run Setup.com /preparead and continue installation

Cheers,

Was Exchange 2010 Uninstalled correctly? It sounds like someone has deleted the admin group that is created by the installation but there is still some trace there.

Have you tried creating a new Admin group with that name? It has to be 100% exact as the error.

Check in the registry for any keys called Watermark under each role in this location.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ExchangeServer\v14.0\

there could be three - MailboxRole, ClientAccessRole and HubTransportRole.

If there is, delete them then run the prep commands again.

I don't know what else to suggest.
When Exchange 2010 was removed you obviously did some extra steps to remove it, perhaps outside of the official Microsoft documentation, but didn't complete them correctly.

You are probably looking at one of two options.

1. A call to Microsoft support, as they will be able to look at the server.
2. A new forest and doing a cross forest migration.
