The Office Deployment Tool is Microsoft's command-line utility for downloading, configuring, and installing Microsoft 365 Apps across managed devices, using XML configuration files to control which products, languages, update channels, and user-facing options a deployment applies.
The Office Deployment Tool (ODT) is a command-line utility that downloads Microsoft 365 Apps installation files and deploys them to client computers with settings you define in advance. You edit a small XML file, then run the setup executable in download, configure, or customize mode to fetch products, install them, or adjust application preferences on machines that already have Office. That workflow replaces clicking through an installer on every device with a single repeatable job. Because products, languages, architecture, update channel, and whether users see any interface all live in the configuration file, administrators get consistent results across a fleet and can automate the Office Deployment Tool through scripts, management platforms, or imaging task sequences.
Deployments rarely end with a first install. The Office Deployment Tool also handles updates, removals, and extra language packs: pointing clients at an internal update location keeps traffic on the local network, while the ExcludeApp and Remove elements strip applications or languages you no longer want. Large organizations download installation files once to a network share and republish them, avoiding a saturated internet link when hundreds of machines install simultaneously. Configuration files can be written by hand or generated in Microsoft's Office Customization Tool and then exported. For contrast, consumer utilities such as Google Desktop address personal desktop search rather than enterprise provisioning, which highlights how narrowly scoped this tool's job is.
Standardizing an Office rollout with the Office Deployment Tool saves time, bandwidth, and support tickets. Instead of touching each device by hand, administrators define products, languages, update channels, and display behavior once, then reuse that same XML file across every machine. Silent installation with the EULA pre-accepted means end users keep working and never face prompts. Download mode lets a company mirror installation files internally, so a fleet-wide upgrade does not hammer the internet connection, and incremental downloads transfer only files that differ from what is already stored. Because the updates path is configurable, updates can be tested on a pilot ring before reaching everyone, and channel selection lets slower-moving groups stay on a more predictable release cadence. Version pinning keeps devices aligned for imaging and testing, while ExcludeApp and Remove let administrators trim unused applications and reclaim disk space. The result is a repeatable, scriptable Office deployment that fits existing management tooling rather than replacing it.
Key capabilities and highlights.
Every deployment decision lives in a configuration.xml file: which products to install, the languages to include, 32-bit or 64-bit architecture, and the update channel. Editing a single document gives administrators precise, reviewable control and makes the same deployment reproducible across an entire fleet.
The tool runs in distinct modes rather than one monolithic routine. Download mode fetches installation files to a folder or network share, configure mode installs, updates, or removes products and languages, and customize mode reapplies application preferences on devices that already have Office without disturbing other settings.
Setting the display level to none and accepting the license terms inside the configuration file produces an installation with no dialogs, no prompts, and no user interaction. That makes the Office Deployment Tool well suited to unattended imaging, remote help-desk sessions, and rollouts where staff should not be interrupted.
Administrators can host installation files on a network share and direct client machines to pull updates from that same location instead of the internet. This keeps expensive WAN or broadband links free during mass installs and gives change control over exactly which build a device receives.
When installation files already exist in the target folder, the tool compares versions and downloads only what is missing. Adding a second language to an existing English source, for example, transfers just the new language pack rather than the full product, which cuts transfer time on repeat builds.
ExcludeApp and Remove elements let administrators omit components such as Publisher or OneDrive during setup, or uninstall a language version that is no longer needed. Trimming unused applications reduces deployment size, simplifies patching, and keeps the Start menu focused on the tools staff actually use.
Choosing a delivery channel, and optionally pinning a specific build, keeps devices aligned with a support plan. Pilots can sit on a faster cadence while stable groups follow a slower one, and version matching lets administrators add language packs without forcing a full upgrade at the same time.

Common questions about Office Deployment Tool.
It is used to download and install Microsoft 365 Apps on client computers using settings defined in an XML configuration file. Administrators rely on it for custom installs, silent rollouts, language and product selection, update management, and removing Office components across many devices at once, instead of installing Office manually on each machine.
No. Configuration files can be written in any text editor, and Microsoft publishes sample XML files alongside the tool. The web-based Office Customization Tool is a convenience: it builds the same kind of configuration file through a guided interface and exports it, which reduces syntax mistakes in complex deployments.
Yes. Setting the display level to none prevents any interface from appearing during setup, and accepting the license terms in the configuration file accepts them on the user's behalf. Combined with a prepared XML file, this produces a genuinely hands-off installation that can run from a script, a management platform, or an imaging task sequence.
You can run configure mode again to move devices to a newer build, or point clients at an internal update path so they pull updates from your own network share. The update channel, and optionally a specific version in the configuration file, decide which build devices receive and how quickly they move.
Yes. The ExcludeApp element omits applications such as Publisher or OneDrive during installation, and the Remove element uninstalls a whole product or language version you no longer want. Those options let administrators keep installations lean and correct decisions made in earlier deployments without rebuilding a device.
No. The same tool supports subscription products such as Microsoft 365 Apps for enterprise alongside volume-licensed editions, and the product IDs in the configuration file determine what is downloaded or installed. Organizations of any size can therefore use the Office Deployment Tool as long as the account used for activation is entitled to the chosen product.
