Home & Student vs Home & Business:
Home & Student includes the four core apps — Word, Excel, PowerPoint, OneNote — and is licensed for personal and educational use only. It does not include Outlook and cannot be used for commercial or business work. If you need Outlook or use Office professionally, choose Home & Business or Pro Plus.

Is this version enough for you?
If you write documents, build spreadsheets, and make presentations — for school, personal projects, or creative work — Home & Student covers everything. It’s the right fit if you already use web-based email (Gmail, Outlook.com) and don’t need the full Outlook desktop app.

What’s included:

Word
Excel
PowerPoint
OneNote
