RMS Shared Identity user FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042 not found.

Hi all.

I have issue while trying to install Exchange 2013.

It is clear and first installation of exchange in my forest. There where no other exchanges in this forest before. This is the first server which i'm installling. And i got error:

Error:
The following error was generated when "$error.Clear();
          if ( ($server -eq $null) -and ($RoleIsDatacenter -ne $true) )
          {
            Update-RmsSharedIdentity -ServerName $RoleNetBIOSName
          }
        " was run: "RMS Shared Identity user FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042 not found.".

After some troobleshooting i found that i don't have federated mailbox. "setup /preparead" from exchange 2013 disc  didn't help. How can i recreate this mailbox? i found some solution as change schema version to exchange 2010 version and with exchange 2010 try to "setup /preparead" but as i understand it is not official solution.
