Script to assign licenses to bulk AD synced user's office 365

Question

i have dirsync so all my local ad users are synced with office 365 tenant
Now I am migrating mailboxes and I need to assign licenses to a bulk migrated users using csv
This process requires 2 steps ‘cmdlts’
$usagelocation = “SA”
Set-MsolUser –UserPrincipalName user@domain -UsageLocation $UsageLocation
After defining the location above time to assign the licenses
 Set-MsolUserLicense –UserPrincipalName user@domain  -AddLicenses company:ENTERPRISEPACK
So how can I script this and use a CSV file?
Also strange thing, I have ran the above to about 13 users manually, I placed the command on a notepad
Copied all lines and past on the PS, after that other users who already had licenses had their licenses removed! So what did I do wrong? I am asking this to make sure the script you will provide will not remove the currently assigned licenses

Answer 1

this script will work for you given the below conditions
1- you have csv file with only one
Column named "UserPrincipalName" and has all users need to be licensed
2- all users in the above file in the format of [email protected]
3- All users are having the same license
$path= Import-Csv -Path "usersFiles.csv"
foreach ($item in $path){
$MSOLUserName= $item.UserPrincipalName
$password = ConvertTo-SecureString "password here" -AsPlainText –Force
$credential = New-Object System.Management.Automation.PsCredential("your username here",$password)
$cred = Get-Credential -cred $credential
Import-Module MSOnline
Connect-Msolservice -cred $cred
$AccountSkuId = "tenantdomain:ENTERPRISEPACK"
$UsageLocation = "SA"
$LicenseOptions = New-MsolLicenseOptions -AccountSkuId $AccountSkuId
Set-MsolUser -UserPrincipalName $MSOLUserName -UsageLocation $UsageLocation
Set-MsolUserLicense -UserPrincipalName $MSOLUserName -AddLicenses $AccountSkuId -LicenseOptions $LicenseOptions
