Add Lync License To Multiple users

Hi

All our users are Licensed for Office365  for EXCHANGESTANDARD.

The company has recently added Lync services.

We several groups of users who need to be licensed for Lync (MCOSTANDARD).

I exported the users from each OU to a CSV file using their UPN. Here is the script that created;

"Import-Csv .\Group1.csv | ForEach_Object

{

$userprincipalname = $_.userprincipalname

(Get-MsolUser -UserPrincipalName $userprincipalname).Licenses[0].ServiceStatus

Set-MsolUserLicense -UserPrincipalName $userprincipalname -AddLicense "tenant:MCOSTANDARD"

}

When I ran the script in ISE the following came up at the prompt;

cmdlet ForEach_Object at command pipeline position 2

Supply values for the following parameter:

Process[0]:

I pressed the ENTER key the entire script output to the screen as  if ran successfully but when I verify the license has not been assigned to the users.

I am new to powershell and will like your help

Thanks
