How to Install Microsoft 365 Apps

Microsoft 365 offers both browser-based and desktop versions of Microsoft Word, PowerPoint, Excel, OneNote, and more. Microsoft 365 Web Apps allow users to view and edit Microsoft 365 documents on any device via a web browser, while the desktop versions allow for offline and more robust document creating and editing.

You can download the Microsoft 365 desktop applications on up to 5 devices.

Please Note: The process that installs the new Microsoft 365 also uninstalls all older Office products. As you might expect, the older Word, Excel, PowerPoint, and the rest of the Office suite are uninstalled to make room for the new applications. You won’t be able to reinstall them.
