Bulk import of mail contacts

[BoomAM]

Hi,
Can anyone tell me whats going wrong here? Im using this cmdlet to try and import some mail contacts in Exchange Powershell

Import-CSV C:\ch.csv | ForEach-Object {New-MailContact -Name ($_."First Name"+" "+$_."Last Name") -DisplayName ($_."First Name"+" "+$_."Last Name") -FirstName $_."First Name" -LastName $_."Last Name" -OrganizationalUnit $_."Organizational Unit" -ExternalEmailAddress $_."EmailAddress" }

But it errors every time on the 6th contact in!

Invoke-Command : Cannot bind parameter 'Name' to the target. Exception setting "Name": "The property value is invalid.
The value can't contain leading or trailing whitespace."
At USER FOLDER PATH
1.contoso.com.psm1:27888 char:29
+ $scriptCmd = { & <<<< $script:InvokeCommand `
+ CategoryInfo : WriteError: ( : ) [New-MailContact], ParameterBindingException
+ FullyQualifiedErrorId : ParameterBindingFailed,Microsoft.Exchange.Management.RecipientTasks.NewMailContact

Any ideas?

Yes.
Ive modified the code to this:

[PS] C:\>Import-CSV C:\ch.csv | ForEach-Object {New-MailContact -Name $_.Name -FirstName $_.First Name -LastName $_.Last
Name -OrganizationalUnit $_.Organizational Unit -ExternalEmailAddress $_.EmailAddress }

And now it errors with this:

A positional parameter cannot be found that accepts argument 'Name'.
