Remove Azure Licence for user from a csv file - azure

Question

I don't know why my script work just for the first line and then I have :
Get-MsolUser : Impossible de convertir «System.Object[]» en type «System.String», requis par le paramètre «UserPrincipalName». La
méthode spécifiée n'est pas prise en charge.
Au caractère Ligne:5 : 34
+ (get-MsolUser -UserPrincipalName $csv2).licenses.AccountSkuId |
+ ~~~~~
+ CategoryInfo : InvalidArgument : (:) [Get-MsolUser], ParameterBindingException
+ FullyQualifiedErrorId : CannotConvertArgument,Microsoft.Online.Administration.Automation.GetUser
My Code :
$csv2 = Import-Csv C:\Tools\LicencesToRemove.csv
for ($i=0; $i -lt $csv2.Count; $i++)
{
(get-MsolUser -UserPrincipalName $csv2).licenses.AccountSkuId |foreach{
Set-MsolUserLicense -UserPrincipalName $csv2 -RemoveLicenses $_
}
}
csv file :
test.delete1#abc.onmicrosoft.com
test.delete2#abc.onmicrosoft.com
test.delete3#abc.onmicrosoft.com
test.delete4#abc.onmicrosoft.com

Answer 1

The issue is here.
get-MsolUser -UserPrincipalName $csv2
The UserPrincipalName must be of type string where as here it is Object[]. I suspect you are intended to write the following within the for loop
get-MsolUser -UserPrincipalName $csv2[$i].YourCsvColumnName

Answer 2

Assuming that your .csv2 file has a header with "UserPrincipalName". You can use the script below.
$csv2 = Import-Csv C:\Tools\LicencesToRemove.csv
foreach($user in $csv2)
{
(get-MsolUser -UserPrincipalName $user.UserPrincipalName).licenses.AccountSkuId |foreach{
Set-MsolUserLicense -UserPrincipalName $user.UserPrincipalName -RemoveLicenses $_
}
}
