Deploy Microsoft 365 apps using Microsoft Intune

Completed

Managing Microsoft 365 apps across your organization requires a deployment strategy that ensures consistency, compliance and reliable updates. Instead of manually installing Office on each device, you can use Microsoft Intune to automate deployment, control which apps users receive and manage update channels centrally.

In this unit, you'll learn how to deploy Microsoft 365 apps to your managed devices through Intune's application management capabilities.

Understanding Microsoft 365 Apps deployment in Intune

Microsoft 365 apps including Word, Excel, Outlook, PowerPoint and OneNote are cloud-connected applications that integrate directly with Intune's management framework. When you deploy Microsoft 365 apps through Intune, you gain cloud-based control over installation, updates and licensing without distributing large installation files to each device.

Intune manages Microsoft 365 apps deployment by packaging the suite with your chosen configuration and delivering it to target devices. The apps then connect to Microsoft 365 services for authentication, document storage and collaborative features. Updates are delivered through Intune using the channel you specify, ensuring all devices stay current with minimal user disruption.

This approach eliminates traditional deployment challenges like managing installation media, tracking licensing and coordinating update schedules across locations and time zones.

Configure deployment options for Microsoft 365 apps

Before deploying Microsoft 365 apps, you specify which apps, versions and update cadence your organization needs. These choices directly impact your deployment strategy and user experience.

Select which apps to include. You don't need to deploy the entire Microsoft 365 suite to every device. Intune lets you choose specific apps based on job roles or department needs. For example, you might deploy Word and Excel to administrative staff but only Outlook to field technicians. This reduces disk space requirements and simplifies user interfaces.

Choose your installation architecture. Microsoft 365 apps are available in 32-bit and 64-bit versions. Most modern devices use 64-bit architecture for better performance with large files and datasets. However, 32-bit versions may be needed for older devices or specific compatibility requirements. Specify your architecture choice during deployment configuration.

Select an update channel. Update channels control how frequently devices receive new features and security updates:

• Current Channel – Delivers new features as soon as they're released, up to three times per month. Use this for users who need the latest capabilities.
• Monthly Enterprise Channel – Provides new features and updates once per month on a predictable schedule. This suits most organizations.
• Semi-Annual Enterprise Channel – Delivers updates every six months with extensive stability testing. Use this for devices that require maximum stability, like kiosks or critical business systems.

Specify language preferences. Configure which language packs are included and which language is the default for the Office User Interface. You can support multiple languages on a single device or require consistent language settings across deployment groups.

Plan your deployment requirements

Before starting your deployment, verify that your environment and devices meet prerequisites.

Check supported operating systems. Microsoft 365 apps require specific Windows versions. Verify that managed devices run Windows 10 or later. Devices running unsupported operating systems won't receive the deployment.

Understand licensing requirements. Users must have appropriate Microsoft 365 licensing to activate and use the apps. Personal device users need Microsoft 365 subscriptions (such as Microsoft 365 Personal or Microsoft 365 Family), while organizational deployments typically use Microsoft 365 Apps for enterprise, Microsoft 365 Business Standard or similar plans. Intune doesn't manage licensing directly, so ensure your licensing framework aligns with your deployment scope.

Plan your network strategy. Microsoft 365 apps are downloaded through cloud content delivery networks (CDNs). Devices with reliable internet connectivity can download directly. For organizations with limited bandwidth, consider using Intune's tenant network bandwidth optimization settings or local caching strategies to manage download traffic.

Deploy Microsoft 365 apps through Intune

The deployment workflow in Intune follows a straightforward process: you create a configuration, assign it to users or devices and monitor installation status.

Create a Microsoft 365 Apps deployment.

1. Open the Microsoft Intune admin center.
2. Navigate to Apps > All apps.
3. Select Add > Windows > Microsoft 365 Apps for Windows 10 and later.
4. On the Configure app suite page, select the applications you want to include (Word, Excel, Outlook, PowerPoint and others), choose your architecture and update channel and specify language settings.
5. Review your selections and select Next.

The configuration page displays all your choices before you commit. This is your opportunity to verify that the deployment matches your organization's needs.

Assign the deployment to users or devices.

While creating the deployment configuration, you assign it to user or device groups. Select your assignment type:

• Required – Intune automatically installs the apps on assigned devices. Users can't uninstall the apps.
• Available – The app appears in the Intune Company Portal and users choose whether to install it.
• Uninstall – Intune removes the apps from assigned devices.

You can refine your assignment by using groups and dynamic filters. For example, you might make the deployment required for CEO and finance team groups but available to other departments. Device filters let you target specific device types or configurations, such as "Windows 10 devices with 4 GB or more RAM."

Manage updates and handle existing installations

Once deployed, Microsoft 365 apps on managed devices follow the update schedule specified in your deployment configuration. Intune controls which update channel devices receive, ensuring consistency across your organization.

Handle existing Office installations. If devices already have older versions of Office (such as Office 2016), Intune can coexist with those versions or replace them. Microsoft 365 apps can run alongside older Office versions, but this increases disk space usage. For a cleaner transition, you can configure Intune to uninstall previous versions during the Microsoft 365 apps installation.

Manage update behavior. Updates deploy automatically on the schedule defined by your chosen update channel. Users receive notifications before updates occur and updates typically complete in the background. You can't delay or customize individual updates through Intune, but you can switch devices to a different update channel if your organization's needs change.

Monitor and troubleshoot deployment outcomes

After deployment, use Intune's reporting features to verify successful installation and identify issues.

Review installation status. In the Intune admin center, go to Apps > All Apps and select your deployment. The status dashboard shows how many devices have the app installed, how many assignments are pending and which devices have installation failures.

Troubleshoot failed installations. If devices fail to install Microsoft 365 apps, check the device logs within Intune's device details. Common causes include insufficient disk space, incompatible operating systems or network connectivity issues.

Track user adoption. Monitor which users and devices have Microsoft 365 apps installed. This helps you identify groups that need additional support, determine if your phased rollout strategy is working and measure the overall success of your deployment.

By deploying Microsoft 365 apps through Intune, you shift from individually managing Office installations to centrally controlling the entire application lifecycle, from initial deployment through ongoing updates and monitoring.
