$DisplayName = "UAT3 TEST"
$FirstName = "UAT3"
$LastName = "TEST"
$UPN = "[email protected]"
$UsageLocation = "MY"
$O365License = Get-MsolAccountSku | ? AccountSkuID -like "*ENTERPRISEPREMIUM" #E5 License

New-MsolUser -DisplayName $DisplayName -FirstName $FirstName -LastName $LastName `
-UserPrincipalName $UPN -UsageLocation $UsageLocation -LicenseAssignment $O365License.AccountSkuID -Password "P@ssw0rd"

Provision Multiple Users from CSV File in Office 365

Prepare a CSV file which contains UserPrincipalName,FirstName,LastName,DisplayName,UsageLocation,AccountSkuId in Excel and save it as CSV (MS-DOS (.csv)** format

Provision users based on the information from imported CSV file

Import-Csv -Path C:\Temp\O365-NewUsers.csv | foreach {
    New-MsolUser -DisplayName $_.DisplayName -FirstName $_.FirstName -LastName $_.LastName `
    -UserPrincipalName $_.UserPrincipalName -UsageLocation $_.UsageLocation -LicenseAssignment $_.AccountSkuId -Password $_.Password} | 
    
Select DisplayName, FirstName, LastName, UserPrincipalName, UsageLocation, Password | Export-Csv -Path C:\Temp\O365-Result.csv -NoTypeInformation 

Users’ Password will be exported to C:\temp\O365-Result.csv and prompted to change their password upon first login

PS C:\Users\admin\Desktop> Get-Content C:\Temp\O365-Result.csv
"DisplayName","FirstName","LastName","UserPrincipalName","UsageLocation","Password"
"UAT4 TEST","UAT4","TEST","[email protected]","MY","Hoc11636"
"UAT5 TEST","UAT5","TEST","[email protected]","MY","Gaz98602"
