Microsoft offers an ocean of applications for various purposes, but not every enterprise environment requires the full suite. For example, IT administrators might only want to deploy Outlook to call center workstations to limit distractions and save system resources, while reserving Excel and Access for finance team desktops. Similarly, an organization may choose to exclude Teams on kiosk PCs used for customer self-service. To help with these scenarios, Microsoft provides the Office Customization Tool, which lets IT teams select specific applications to install or exclude, as well as choose between 64-bit or 32-bit architectures.
Before jumping to the Office Customization Tool download and configuration, let’s clear the basics around what exactly this tool is and its role.
What Is the Office Customization Tool
Simply put, the MS Office Customization Tool is a web-based utility for IT administrators that allows them to create customized XML configuration files to deploy Microsoft 365 apps and other Click-to-Run MS Office products.
Used together with the Office Deployment Tool, the Office Customization Tool rolls out tailored Office installations across a network, offering complete control over installation, including selection of apps, language packs, licensing, and update channels.
Please note that since the Office Customization Tool (OCT) is a web-based tool, you cannot really download it. What you create with the OCT is a configuration file in XML format, which defines your desired Office installation settings. You then use the Office Deployment Tool (ODT), which you can download from Microsoft, to deploy Office using your custom configuration file.
In summary, the workflow is: create the configuration XML in the OCT, then use the ODT to perform the actual deployment. The Office Deployment Tool is an essential component for deploying Microsoft Office with the Office Customization Tool.
Now that you have a better understanding of the MS Office Customization Tool, let’s help you use it.
