Deployment and Distribution Using Active Directory and Intune
Distributing Microsoft 365 Enterprise apps to end-user devices can be automated using Group Policy (AD) for traditional environments and Microsoft Intune for modern, cloud-first environments.

Option 1: Deploying Microsoft 365 Enterprise via Intune (Recommended for Modern Environments)
Microsoft Intune allows organizations to push Microsoft 365 apps to managed Windows 10/11 devices.

Prerequisites:
Devices must be enrolled in Intune

Azure AD Premium license

Intune admin role

Steps to Deploy Microsoft 365 Apps via Intune:
Login to Microsoft Endpoint Manager Admin Center

URL: https://endpoint.microsoft.com

Go to Apps > Windows > + Add

Select App Type:

App type: Microsoft 365 Apps for Windows 10 and later

Configure App Suite Settings:

Choose architecture (32/64-bit)

Select apps to include (e.g., Word, Excel, Outlook)

Remove unwanted apps (e.g., OneNote if already installed)

Configure update channel (Current/Monthly Enterprise)

Assign the App:

Choose assignment groups (e.g., “All Devices” or “Sales Team”)

Review and Create

PowerShell Script for Monitoring Installation via Intune
powershell
`

`

Check for Office installation on a remote Intune-managed device

$deviceName = "Laptop-01"
$script = {
Get-WmiObject -Query "SELECT * FROM Win32_Product WHERE Name LIKE 'Microsoft 365%'" |
Select-Object Name, Version
}

Invoke-AzVMRunCommand -ResourceGroupName "RG-IntuneDevices" -Name $deviceName -CommandId 'RunPowerShellScript' -Script $script
`
`
This method is best suited for Azure VMs or hybrid Azure AD-joined devices. For local environments, use remote PowerShell sessions or rely on Endpoint Manager reporting tools.

Option 2: Deploying Microsoft 365 via Group Policy or Active Directory
Organizations using on-premises Active Directory can deploy Microsoft 365 Apps using startup scripts or Configuration Manager (SCCM).

Steps to Deploy via GPO Startup Script:
Download Microsoft 365 Deployment Tool

URL: https://www.microsoft.com/en-us/download/details.aspx?id=49117

Create Configuration XML

xml

<Configuration>
  <Add OfficeClientEdition="64" Channel="MonthlyEnterprise">
    <Product ID="O365ProPlusRetail">
      <Language ID="en-us" />
    </Product>
  </Add>
  <Display Level="None" AcceptEULA="TRUE" />
  <Property Name="AUTOACTIVATE" Value="1" />
</Configuration>

Place setup.exe and configuration.xml in a shared network location.

Create a GPO Startup Script

batch

\\YourDomain\Shared\OfficeDeploy\setup.exe /configure \\YourDomain\Shared\OfficeDeploy\configuration.xml
Apply GPO to Organizational Unit (OU) containing target computers.

PowerShell Alternative Using AD
powershell
Copy
Edit
Invoke-Command -ComputerName "Client-PC" -ScriptBlock {
    Start-Process -FilePath "\\domain.local\Deploy\Office\setup.exe" -ArgumentList "/configure \\domain.local\Deploy\Office\configuration.xml" -Wait
}

Make sure devices allow PowerShell remoting and can access the network deployment share.

Best Practices for Enterprise Deployment
Use Pilot Groups
Test deployments on a small user group before enterprise-wide rollout.

Modular Configuration Files
Maintain different XML configurations for different departments or needs.

Enable Telemetry and Compliance
Use Microsoft Endpoint Analytics and Compliance Manager to monitor installation and policy compliance.

Shared Activation
Ideal for lab or shared environments such as front-desk terminals.

License Monitoring
Reassign licenses based on usage insights from the Microsoft 365 Admin Center.

Monitoring and Reporting
Endpoint Manager Console – Monitor install success rates, assign apps by group

Azure AD Logs – Analyze sign-ins and application usage

Microsoft 365 Admin Center – View health, activation status, and service issues

Power BI or Microsoft Graph API – Build custom dashboards for visibility
