Microsoft 365 includes Word, Excel, PowerPoint, Outlook, OneDrive, Teams, and depending on your plan, OneNote, Publisher, Access, SharePoint and more — a full productivity suite plus 1 TB of cloud storage per person. Most subscribers use only a fraction of what they pay for, so understanding what each app does helps you get full value. Here's every major app explained and who benefits most from each.
The core four: what everyone uses
Word is the word processor for documents, reports, letters and proposals — the standard for professional writing. Excel is the spreadsheet powerhouse for budgets, data analysis, forecasts and tracking — its formulas, pivot tables and charts make it the most-used business tool in the suite. PowerPoint builds presentations and slide decks for meetings, pitches and teaching. Outlook handles email, calendar, contacts and tasks in one place, with business email on your own domain. These four cover the daily needs of most users.
OneDrive: your 1 TB of cloud storage
Every Microsoft 365 plan includes 1 TB of OneDrive cloud storage per person — and it's more than a hard drive in the sky. OneDrive automatically backs up your documents, syncs them across all your devices, lets you share files with clients via links, and keeps version history so you can recover earlier drafts or deleted files. For anyone without a server or NAS, OneDrive is your file infrastructure, and the 1 TB included in the subscription would cost money on its own elsewhere.
Microsoft Teams: communication central
Teams combines chat, video meetings, file sharing and app integration into a single workspace. For businesses, it replaces scattered email threads, separate video tools and messaging apps — conversations, meetings and files for a project all live in one place. Meeting recordings, screen sharing, channels per team or client, and tight Office integration make it the collaboration hub of the suite, especially for remote and hybrid teams.
OneNote: the underrated notebook
OneNote is a freeform digital notebook for capturing ideas, meeting notes, research and to-do lists, organized into notebooks, sections and pages. It syncs across devices and supports typed notes, handwriting, images and audio. It's less flashy than the core apps but genuinely useful for keeping information organized and searchable — many people who try it wonder how they managed without it.
Publisher and Access (PC only)
Publisher creates print-ready materials — brochures, flyers, newsletters, business cards — with easier layout tools than Word. Access is a database tool for building custom data-tracking applications without full programming. Both are PC-only and aimed at specific needs: Publisher for marketing materials, Access for businesses that need custom databases beyond what Excel handles.
SharePoint and the business apps
Business plans add SharePoint (a central team file library and intranet), Exchange (business email hosting), and admin/security tools. SharePoint becomes your company's shared file system and internal site once personal OneDrives aren't enough. These transform Microsoft 365 from a personal productivity suite into an organizational platform.

Getting full value from your subscription
The common mistake is paying for Microsoft 365 and only using Word and Excel. The real value comes from adopting OneDrive for backup and sharing, Teams for communication, and OneNote for organization — features that replace other paid tools. For businesses, adding SharePoint and Exchange consolidates even more. A subscription that covers Office plus 1 TB storage, email and collaboration tools is often cheaper than buying those separately.
The bottom line
Microsoft 365 bundles Word, Excel, PowerPoint and Outlook with 1 TB of OneDrive, Teams, OneNote and more — a complete productivity ecosystem, not just Office apps. Use the full suite and it replaces several separate subscriptions. DigitalTools sells Microsoft 365 plans with instant activation at below-retail prices, so you get the entire ecosystem for less.
