Error during install "$error.Clear();

Question

Hi everyone,
Next error popped up while installing exchange 2013:
The following error was generated when "$error.Clear();
          if (($RoleIsDatacenter -ne $true) -and ($RoleIsDatacenterDedicated -ne $true))
          if (test-ExchangeServersWriteAccess -DomainController $RoleDomainController -ErrorAction SilentlyContinue)
          $sysMbx = $null;
          $name = "SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}";
          $dispname = "Microsoft Exchange";
          $mbxs = @( get-mailbox -arbitration -Filter {name -eq $name} -IgnoreDefaultScope -resultSize 1 );
          if ( $mbxs.length -eq 0)
          $dbs = @(get-MailboxDatabase -Server:$RoleFqdnOrName -DomainController $RoleDomainController);
          if ($dbs.Length -ne 0)
          $arbUsers = @(get-user -Filter {name -eq $name} -IgnoreDefaultScope -ResultSize 1);
          if ($arbUsers.Length -ne 0)
          $sysMbx = enable-mailbox -Arbitration -identity $arbUsers[0] -DisplayName $dispname -database $dbs[0].Identity;
          else
          if ($mbxs[0].DisplayName -ne $dispname )
          set-mailbox -Arbitration -identity $mbxs[0] -DisplayName $dispname -Force;
          $sysMbx = $mbxs[0];
          # Set the Organization Capabilities needed for this mailbox
          if ($sysMbx -ne $null)
         Write-ExchangeSetupLog -Info ("Setting mailbox properties.");
          set-mailbox -Arbitration -identity $sysMbx -UMDataStorage:$true -Force;
          # No RetentionPolicy assigned to E-Discovery arbitration mailbox currently, we need to set it here.
          # This can be remove after BUG(O15#2555914) is fixed.
          if ($sysMbx.RetentionPolicy -eq $null )
          $arbitrationRetentionPolicy = @(Get-RetentionPolicy -DomainController $RoleDomainController | where {$_.Name -eq 'ArbitrationMailbox'});
          set-mailbox -Arbitration -identity $sysMbx -RetentionPolicy $arbitrationRetentionPolicy[0].Identity -Force;
          else
          Write-ExchangeSetupLog -Info ("Cannot find E-discovery arbitration mailbox with name=$name.");
          else
          write-exchangesetuplog -info "Skipping creating Discovery Arbitration Mailbox because of insufficient permission."
        " was run: "Database is mandatory on UserMailbox.".
I can't find where it goes wrong. Can anyone help me?
Thanks

Hi,
Please check the homeMDB attribute of the system mailbox "SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9}", make sure the homeMDB attribute points to the correct mailbox database.
If the value of homeMDB attribute is ok, please recreate this system mailbox to check result.
