When a portable approach can be reasonable

Microsoft only provides offline installers for standard installation. Most "portable" versions are created by third parties and may be found on community sites like The House of Portable .

Files are saved to OneDrive, allowing you to access them from any computer with a browser. 2. Using the Office Offline Installer

Microsoft offers free web-based versions of Word, Excel, and PowerPoint. All you need is a Microsoft account (Outlook/Hotmail). You can access these from any computer with a browser, making them essentially "portable."

Ideally, a would allow you to plug a USB drive into any Windows PC and instantly launch Word, Excel, and PowerPoint without needing admin rights to install software.

The biggest draw is the lack of installation. You don’t need administrative privileges to "install" the software. This is particularly useful for students using library computers or professionals working on restricted workstations where software installation is blocked. 2. Space-Saving

Microsoft does not officially offer a "portable" version of Office 2019 that can be run from a USB drive without installation. Historically, Microsoft provided a feature for specific versions, but this is not available for Office 2019.
