Download and Install Microsoft Office 365

What the Office 365 Installer does

This Automox Worklet™ automates the download and installation of Microsoft Office 365 on macOS endpoints. The Worklet retrieves the full Office suite installer package directly from Microsoft's distribution network at go.microsoft.com, which contains Word, Excel, PowerPoint, Outlook, OneNote, and OneDrive.

The installation process downloads the PKG file to a temporary location, runs the macOS installer utility to deploy all Office applications, and cleans up the downloaded package. The Worklet checks for the presence of Microsoft Excel.app to determine if Office is already installed before initiating a download.

Why deploy Office 365 through Automox

Manual software deployment creates inconsistencies and delays across endpoints. Deploying Microsoft Office 365 through Automox eliminates the need for users to download and install the suite themselves. This saves significant time since the Office installer is over 8 GB and requires administrator privileges to install system components.

Standardizing Office deployment across your fleet provides a consistent productivity environment for all users. You can combine this Worklet with scheduled policies to automatically deploy Office to new endpoints or reinstall it when users accidentally remove applications.

By pulling directly from Microsoft's servers, you deploy the current version without maintaining local installer caches. This approach reduces storage requirements while keeping Office deployments current.

How Office 365 installation works

1. Evaluation phase: The Worklet immediately triggers remediation by exiting with code 1. This design allows the Worklet to reinstall Office if removed, or you can run it once for initial deployment.

2. Remediation phase: The script checks if /Applications/Microsoft Excel.app exists. If Office is not present, it downloads the full installer PKG from go.microsoft.com (linkid=525133), runs the macOS installer command targeting the root volume, and removes the temporary PKG file. If Office already exists, the script skips installation.

Office 365 installation requirements

• macOS Big Sur, Monterey, Ventura, or later

• Intel or Apple Silicon (M1/M2) processor

• Network access to go.microsoft.com

• At least 10 GB free disk space for download and installation

• Valid Microsoft 365 license for activation (installation works without license)

• Extended Worklet timeout due to large download size (8+ GB)

Expected state after Office 365 installation

After successful remediation, the full Microsoft Office 365 suite appears in the /Applications folder. This includes Microsoft Word, Excel, PowerPoint, Outlook, OneNote, and OneDrive applications. Users can launch any Office application immediately, though they need to sign in with their Microsoft 365 account to activate the license. You can verify this change through the Automox Activity Log or by checking the endpoint configuration directly.

You can verify the installation by checking for /Applications/Microsoft Excel.app or by running the Worklet in evaluation-only mode. The Worklet logs indicate whether Office was freshly installed or already present on the endpoint.

How to validate download and install microsoft office 365 changes

1. Run this Worklet on a pilot macOS endpoint and review evaluation output for download and install microsoft office 365.

2. Confirm Automox activity logs show successful completion and exit code 0.

3. Verify endpoint state using checks aligned to evaluation script logic, such as exit.

4. Validate remediation effects from script operations such as curl, installer, rm, then rerun evaluation for compliance.
