Import Data issue from CSV to AD - powershell

Question

I have a problem importing phone numbers from a CSV file based on email addresses to Active directory using a PowerShell script.
The table contains:
mail;telephoneNumber
toto#domaine.com;88888888
tata#domaine.com;99999999
here’s the code I’m running but it shows me an error message, or I don’t see why there’s this message:
Import-module ActiveDirectory
Import-CSV E: scripts list.csv |
ForEach-Object {
Write-Host "telephoneNumber $($_.telephoneNumber)"
Get-ADUser -Filter "mail -like '$($_.mail)'" |
Set-ADUser -telephoneNumber $_. telephoneNumber}
Here is the error message:
telephoneNumber
Set-ADUser: Unable to find a parameter corresponding to the name «telephoneNumber».
Character E: scripts employeeid.ps1:6: 14
+ Set-ADUser -telephoneNumber $_. telephoneNumber}
+ ~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [Set-ADUser], ParameterBindingException
+ FullyQualifiedErrorId: NamedParameterNotFound,Microsoft.ActiveDirectory.Management.Commands.SetADUser
NB: I am a beginner in the subject
Thank you well in advance for your help
I tried this code too but still the same problem.
Import-module ActiveDirectory
Import-CSV "E:\scripts\liste.csv" | % {
$telephoneNumber = $_.telephoneNumber
$mail= $ail_.m
Set-ADUser $telephoneNumber -mail $mail
}

Answer 1

The LDAP property telephoneNumber is known as OfficePhone in PowerShell and LDAP property mail has a PowerShell equivalent called EmailAddress.
Cmdlet Set-ADUser does not have a parameter called telephoneNumber, but it does have OfficePhone, so a rewrite of your code would be
Import-Module ActiveDirectory
Import-Csv -Path 'E:\scripts\list.csv' | ForEach-Object {
$user = Get-ADUser -Filter "mail -eq '$($_.mail)'" # or use PS equivalent 'EmailAddress'
if ($user) {
Write-Host "Setting telephoneNumber $($_.telephoneNumber) for $($user.Name)"
$user | Set-ADUser -OfficePhone $_.telephoneNumber
# if you do want to use LDAP property telephoneNumber, you can use below
# $user | Set-ADUser -replace #{telephoneNumber = $($_.telephoneNumber)}
}
else {
Write-Warning "Could not find user with EmailAddress $($_.mail)"
}
}
P.S. you made some typos when posting:
E: scripts list.csv is missing the backslashes
$_. telephoneNumber has a space between the dot and the property name
