MS-900 Describe Microsoft 365 apps and services Practice Question
A user wants to access their work files from a personal laptop without installing any Microsoft 365 Apps. Which web-based service allows them to view and edit documents in a browser?
⚠ Common exam trap
Microsoft often tests the distinction between storage services (OneDrive, SharePoint) and the actual web-based editing service (Microsoft 365 for the web), causing candidates to mistakenly choose OneDrive because it is the most familiar file-access option.

Correct answer & explanation
✓
Microsoft 365 for the web
Microsoft 365 for the web (formerly Office Web Apps) provides browser-based versions of Word, Excel, PowerPoint, and OneNote, enabling users to view and edit documents without installing any local applications. This service is accessed through a web browser on any device, including a personal laptop, and requires only an internet connection and a valid Microsoft 365 subscription.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Microsoft OneDrive
Why it's wrong here
Microsoft OneDrive is a cloud storage and synchronization service that mirrors files to a user's local device and makes them accessible across platforms. When a user opens an Office file from OneDrive, it launches either the locally installed desktop application or a web-based Office app, but OneDrive itself does not provide any editing interface or document manipulation tools. Therefore, while OneDrive facilitates access to the files, it is not the standalone editor required for this scenario.
- ✓
Microsoft 365 for the web
Why this is correct
Microsoft 365 for the web, formerly known as Office Online, delivers browser-based versions of Word, Excel, PowerPoint, and other Office applications. It allows users to view, create, and edit documents directly in a web browser without requiring any local installation, making it ideal for accessing work files from a personal laptop. As long as the user has an internet connection and appropriate licensing, they can use these web apps for full editing capability, which directly addresses the user's need.
- ✗
Microsoft Teams
Why it's wrong here
Microsoft Teams is primarily a unified communication and collaboration platform that combines persistent chat, online meetings, and team channels with file sharing capabilities. Although Teams includes a Files tab that lets users upload, download, and preview documents, the actual editing is not performed by Teams itself; it relies on external apps like Microsoft 365 for the web or desktop Office suites. Thus, Teams acts as a container for collaboration rather than as the dedicated editing tool the user is seeking.
- ✗
Microsoft SharePoint
Why it's wrong here
Microsoft SharePoint is a document management and collaboration platform that organizes content into sites, libraries, and lists with granular permissions and metadata management. While documents stored in SharePoint can be opened and edited, SharePoint itself does not render or modify the contents; instead, it delegates editing to web-based Office apps or desktop installations. Its core value lies in governance, versioning, and access control, not in providing the direct editing experience needed for the user's personal laptop scenario.
