2. Create client application in Azure for the AD Synctool

Note: The synctool and support is available to our Partners. Are you a New Day at Work Partner and interested? Please contact support@newdayatwork.com

Be aware that you need to install Microsoft SQL Server Compact 4.0

 These are the steps to create the Client App in AAD:

  • Open: "Provision AAD Sync application.ps1" (provided with the synctool) or listed below.
  • Run this script as Admin.
  • Fill in the Admin credentials of the corresponding Office365 tenant.
  • Save and copy all the related information.


We recommend to create the required Azure AD application via PowerShell. Therefore PowerShell will create the application and displays the required information.


$Credentials = Get-Credential
Login-AzureRmAccount $Credentials # Convert the password for W365 format
$SecurePassword = $Credentials.Password
$BSTR = [System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($SecurePassword)
$W365Password = [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($BSTR) $o365user = $Credentials.UserName
$o365password = "$W365Password"

# Get the tenantname from Microsoft
Connect-MsolService -Credential $Credentials
$TenantName = (Get-MsolDomain | Where-Object {$_.Name -like '*.onmicrosoft.com'}).Name.Split('.')[0]

#Fill parameters oAuth2 application
$Operation = "add" #
$Name="Workspace365 AAD Sync" # Name of the application which is created in the Azure AD.
[Parameter(Mandatory=$True)][string[]]$ReplyUrl=@("https://AADSynctool.com") # Check if we are in the correct AD Tenant
