PowerShell says '%' and `New-Object` are not found. Am I missing an import? WinRM, or Exchange Role permission?

Question

Suppose I already configured IIS to allow the remote runspace of "full", how do I resolve the exception that I'm getting where Powershell says "%" is not found.

Then when I comment out the offending for..each statement, it says New-Object can't be found.

Am I missing an import? Based on the comments, it's possible that I'm missing some configuration in WinRM, or an Exchange 2010 role permission.

public static void testExchangeMBScript()
{
  PSCredential credential = new PSCredential(@"domain\me", createPassword("pw"));

WSManConnectionInfo connectionInfo = new WSManConnectionInfo(false, "exchangehost.company.com", 80, "/Powershell", "http://schemas.microsoft.com/powershell/Microsoft.Exchange", credential);

connectionInfo.AuthenticationMechanism = AuthenticationMechanism.Default;

Runspace runspace = System.Management.Automation.Runspaces.RunspaceFactory.CreateRunspace(connectionInfo);

try
{
    runspace.Open();
    Pipeline pipeline = runspace.CreatePipeline();

    string ps1 = "Get-MailboxDatabase -Status";
    string PSFull = @" $Databases = Get-MailboxDatabase -Status
    foreach($Database in $Databases) {
        $DBSize = $Database.DatabaseSize
        $MBCount = @(Get-MailboxStatistics -Database $Database.Name).Count

        $AllMBStats = Get-MailboxStatistics -Database $Database.Name    
     $MBItemAssocCount = $AllMBStats   |   %{$_.AssociatedItemCount.value} |  Measure-Object -Average   -Sum
     $MBDeletedCount =   $AllMBStats   |   %{$_.DeletedItemCount.value} |  Measure-Object -Average   -Sum

Try creating a local runspace, and importing the Exchange 2010 commands from within that PS1

Answer 2

The remote session is a constrained runspace. It doesn't allow you to use cmdlets you're wanting for your script. I believe what you'll need to do is use an unconstrained local runspace, and then from there run the Exchange management cmdlets in the remote runspace using invoke-command:

$AllMBStats = invoke-command {Get-MailboxStatistics -Database $databasename} -argumentlist $database.name -connectionuri "http://exchangehost.company.com/powershell"

Then work with the return from that in the local runspace.
