Add 365 License with Powershell Script in task Scheduler - powershell

Question

I'm trying to license my users in office365 with a powershell script in tassk scheduler.
First : I have a script to create some users in my domain controller. This script add content (userprincipalname) in a txt file. Example :
- Create user : John Smith
- The script add this in the txt file : john.smith#domain.com
Second : Another script try to license this user. This script are connecting to MSOLService with this cmdlets :
$LOGIN = "svc-365#domain.com"
$MDP = Get-Content "C:\Script\SVC-365.txt" | ConvertTo-SecureString
$Cred = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $LOGIN,$MDP
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection
Connect-MsolService -Credential $UserCredential
Import-PSSession $Session -AllowClobber
$User = Get-Content "C:\Script\CreationMail.txt"
foreach ($i in $User) {
Set-MsolUser -UserPrincipalName $i -UsageLocation "FR"
Set-MsolUserLicense -UserPrincipalName $i -AddLicenses "tenantudl:STANDARDWOFFPACK_FACULTY"
}
This script is perfectly working when I manually execute in powershell ISE, but not working in the task scheduler...
If somebody can help me, I will be grateful to him ! :)
Thanks for help !

Answer 1

Which user runs the script in your task?
With credentials that you have saved as a hash value in a text file it can only be decrypted by the user that made the file.
So if you made that file with your user, but the user that is setup to run the task is not the same, say a service account, it cannot decrypt the password and the login will fail.
As a note, I would highly recommend Microsofts new feature to assign licenses by group membership instead of doing it by scripts as Microsoft changes things an scripts break.
It is in preview right now and require an AD Basic license on your account or higher, you can activate a free trial of the EMS license pack in Azure and and this will be enough to activate the feature.

Answer 2

For TaskScheduler scripts, you need to set it up correctly.
Set the "Program/Scritp" to Powershell.exe
Set the "Add arguments" to -ExecutionPolicy Bypass C:\Temp\AddLicence.ps1
(Optional) If your script requires any params then you will need to add them and your "Add Arguments" field ends up as -ExecutionPolicy Bypass C:\Temp\AddLicence.ps1 -Users C:\temp\users.csv -LicenceType C:\temp\O365.txt
