IT administrators need a centralized method to distribute custom corporate THMX themes for Excel and PowerPoint to multiple users.

How to Deploy Excel and PowerPoint THMX Themes with Intune

Product: Microsoft Excel, Microsoft PowerPoint, Microsoft Intune
Device & OS: Windows, Mac
Scenario: Deploying standard corporate branding files (THMX) across an organization so users can seamlessly access them.
Observed behavior: The deployed themes must automatically appear for users within the Office applications under Design > Themes > Custom.

Before you start

Ensure you have Microsoft Intune administrator privileges and your final .thmx theme files are fully prepared and tested on a local device before mass deployment.

Solution 1Recommended

Deploy THMX Files to Local AppData via Intune Scripts

Use Microsoft Intune PowerShell scripts to copy the theme files directly into the local AppData folder on users' Windows machines.

This method forces the theme files into the exact local directory that Office scans for custom templates and themes. It is highly effective for Windows environments.

Create a PowerShell Script

Write a script that copies your corporate .thmx files to the destination path: %appdata%\Microsoft\Templates\Document Themes.

Upload to Microsoft Endpoint Manager

Log in to the Intune portal, navigate to Devices > Scripts, and add a new Windows PowerShell script containing your deployment code.

Assign to User Groups

Select the target Azure AD user or device groups and deploy the script. Once executed, users will find the themes under Design > Themes > Custom.

Deploy THMX Files to Local AppData via Intune Scripts

Testing Deployment: Verify the deployment on a test machine by opening PowerPoint and checking if the custom theme appears in the Design ribbon before rolling it out organization-wide.

Solution 2

Use an Organization Assets Library in SharePoint

Configure a centralized Organization Assets Library in SharePoint to host corporate themes without managing local file copies.

Solution 3

Deploy Themes using Group Policy (GPO)

For on-premises or hybrid domain environments, Group Policy Preferences can securely push the THMX files to networked machines.

Frequently Asked Questions

Where are PowerPoint THMX files stored locally on a Windows PC?

By default, custom themes are stored in the user's AppData directory at %appdata%\Microsoft\Templates\Document Themes. Files placed here automatically show up under the Custom Themes tab.

Can I deploy THMX themes to Mac users via Intune?

Yes, but instead of PowerShell, you must use a macOS shell script via Intune to copy the .thmx files to the specific macOS Office template directory: ~/Library/Group Containers/UBF8T346G9.Office/User Content/Themes.

Why aren't my deployed themes showing up in PowerPoint?

Ensure the deployment script succeeded and the files physically exist in the target %appdata% directory. If the files are present, the user may simply need to restart Excel or PowerPoint for the application to detect the new themes.

What is the difference between an Office Template (.potx) and an Office Theme (.thmx)?

A .potx template contains slides with specific layouts, text, and structure. A .thmx theme only contains design elements like color palettes, fonts, and background effects, which can be universally applied across PowerPoint, Excel, and Word.
