Get-AzureADUser | Where {$_.Surname -eq $null -and $_.GivenName -eq $null -and $_.UserType -eq "Member"} | Select UserPrincipalName, DisplayName

Setting User Display Name

Write-host $User.UserPrincipalName " will be named $NewDisplayName" - ForegroundColor Green
Set-AzureADUser -ObjectId $user.ObjectId -DisplayName $NewDisplayName
