How to Get Creation Date of Microsoft 365 Users using PowerShell

This article will show you how to get the creation date of all your Azure Active Directory users using a PowerShell script. This is important for auditing purposes and can be used in other scripts to remove any users that were created after a certain date.

Export Creation Date Entra ID Users

1️⃣ First, you must install Entra ID PowerShell module and Connect to Entra ID PowerShell.

Optional: If you don’t have it, let’s open Windows PowerShell as administrator then run the following cmdlets:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine -Force
Install-PackageProvider -Name NuGet -Force
Set-PSRepository -Name "PSGallery" -InstallationPolicy Trusted
Install-Module -Name AzureAD
Import-Module AzureAD
Connect-AzureAD

2️⃣ Run the following script to export the creation date of all users in your Azure Active Directory.

$DataArray = @()
$ADUsers = get-azureaduser -all:$true
foreach($User in $ADUsers) {
    $Creation = Get-AzureADUserExtension -objectid $user.UserPrincipalName
    $UserUPN = $user.UserPrincipalName
    $UserDisplayName = $User.DisplayName

    $TableRow = "" | Select DisplayName, UserPrincipalName, CreationDate
    $TableRow.DisplayName = $UserDisplayName
    $TableRow.UserPrincipalName = $UserUPN 
    $TableRow.CreationDate = $Creation.createdDateTime

   $DataArray += $TableRow
}

If you want to export the result to a CSV file, let’s run the following command.

$DataArray | Export-Csv C:\Report_CreationDate.csv -Nti

Get the creation date for a single user

In some cases, you just need the creation date of a single users instead of all users in your organization. Let’s using the following command.

(Get-AzureADUserExtension -objectid [email protected]).createdDateTime

Script using PSCustomObbject

$Report = @()
$Users = Get-AzureADUser -All:$true
foreach ($User in $Users) 
{

    $ObjReport = [PSCustomObject]@{
    DisplayName = $User.DisplayName    
    UserPrincipalName     = $User.UserPrincipalName
    CreationDate  = (Get-AzureADUserExtension -ObjectId $User.ObjectId).Get_Item("createdDateTime")
    }

$Report += $ObjReport

}
