Query recently created users in Azure AD

Recently had a project where we wanted to identify users created an automated process in the last day. This script gets the job done.

#Gather a list of recently created users

#specify time that will be compared against -24 is the most recent 24 hours
#you can use the option funtion addDays for a longer time period
#Note that time from AzureAD is UTC

$time = (get-date).ToUniversalTime().AddHours(-24)

$users = Get-AzureADUser -All

$newusers = New-Object Collections.Generic.List

foreach ($u in $users) {
    # Write-Host $u.ExtensionProperty.createdDateTime
    If ([datetime]$u.ExtensionProperty.createdDateTime -gt $time) {
        $newusers.Add($u)
    }
}

Write-host "There are " $newusers.count " new users"
$newusers
