### Step 1: Import the Active Directory Module
Before running the script, ensure that the Active Directory module is loaded in your PowerShell session. This module contains the necessary cmdlets for managing Active Directory.
“`powershell

Import-Module ActiveDirectory

### Step 2: Prepare Your CSV File
Create a CSV file with the required user information. Each row should contain the username (SamAccountName) and the new phone number you wish to set.
Example `phone_updates.csv`:
“`
UserName,PhoneNumber
jdoe,123-456-7890
jsmith,987-654-3210
“`
### Step 3: Define the Function to Update User Phone Numbers
Next, create a function named `Update-ADUserPhoneNumbers` that reads from the CSV file and updates the phone numbers for each user.
“`powershell

function Update-ADUserPhoneNumbers {
    param (
        [string]$csvPath
    )
    $users = Import-Csv -Path $csvPath
    foreach ($user in $users) {
        $username = $user.UserName
        $phoneNumber = $user.PhoneNumber
        try {
            Set-ADUser -Identity $username -TelephoneNumber $phoneNumber
            Write-Host "Successfully updated phone number for user: $username"
        } catch {
            Write-Host "ERROR: Could not update phone number for user: $username. Error: $_"
        }
    }
}

### Step 4: Execute the Phone Update Function
Now, you can execute the function to update the phone numbers as specified in your CSV file.
“`powershell

Update-ADUserPhoneNumbers -csvPath "C:\Path\To\Your\phone_updates.csv"
