### Step 1: Import the Active Directory Module
Ensure that you have the Active Directory module available in your PowerShell session. This module contains all necessary cmdlets to manage Active Directory users.
“`powershell

Import-Module ActiveDirectory

### Step 2: Define the Function to Clean Up Inactive Accounts
We will create a function named `Remove-InactiveADUsers` that identifies user accounts that havent been logged into for a specified number of days and proceeds to remove them.
“`powershell

function Remove-InactiveADUsers {
    param (
        [int]$DaysInactive = 90
    )
    $timeThreshold = (Get-Date).AddDays(-$DaysInactive)
    $inactiveUsers = Get-ADUser -Filter { LastLogonDate -lt $timeThreshold } -Properties LastLogonDate
    foreach ($user in $inactiveUsers) {
        try {
            Remove-ADUser -Identity $user.SamAccountName -Confirm:$false
            Write-Host "Deleted inactive user: $($user.SamAccountName)"
        } catch {
            Write-Host "ERROR: Could not delete user: $($user.SamAccountName). Error: $_"
        }
    }
}

### Step 3: Execute the Cleanup Function
Now, execute the function to perform the cleanup. You can specify how many days define an inactive account.
“`powershell

Remove-InactiveADUsers -DaysInactive 90
