Now I need to check following conditions:
Othertelephone =  if this should not be blank ,if so display message " filed is blank " and no changes should allowed in further attributes and  it should abort
language= this field should only contain  EN or FR value if No display msg " error in language field " and no further changes to  the user attributes and it should abort
employeeID= this field should only contain OTP or SMS value if Not filled display msg " error in Employee ID field " No further changes to the user attributes and it should abort

Hello JRV,Thank you for your time, There is no comma in my csv file , I double check. below I wrote a simple code.I removed all the conditions and just try to set the EmployeeID and it is working fine with same file.But as soon as I add conditions it gives access denied. as well as if I remove employee Id from your previous code and only try to set telephone No. still it gives access denied.I am just trying to figure out what is causing this.
$group=Get-QAdGroup -SearchRoot "com/Group"
Import-Csv D:\VPN.csv |
ForEach-Object{
if ($_.samaccountname -eq ""){
Write-Host "SAMACCOUNTNAME is blank" -fore red
}else{
$user=Get-QAduser $_.samaccountname
if ($user.memberof -contains $group.DN){
Write-Host "$($_.Samaccountname) user is allready a member" -fore red
}else
Add-QADGroupMember $group $_.Samaccountname
If ($_.othertelephone -ne "")
Set-QADUser $user.SamAccountName -ObjectAtt Aributes @{telephonenumber=$_.othertelephone}
} else
Write-Output "$($_.samaccountname) phonenumber is blank"
If ($_.EmployeeID -ne "")
Set-QADUser $_.SamAccountName -ObjectAttributes @{EmployeeID=$_.EmployeeID}
}else
Write-Output "$($_.samaccountname) EmployeeID field is blank"
If ($_.Preferredlanguage -ne "")
Set-QADUser $_.SamAccountName -ObjectAttributes @{Preferredlanguage=$_.preferredlanguage}
} else
Write-Output "$($_.samaccountname) PreferredLanguage field is blank"
