MS-900 Describe Microsoft 365 apps and services Practice Question
Which TWO Microsoft 365 apps can be used to create and edit documents collaboratively in real time? (Select exactly 2.)
⚠ Common exam trap
Candidates often confuse Microsoft Teams as a document editing app because it allows file sharing and preview, but it does not natively provide the real-time collaborative editing capability; that is a feature of the web versions of Office apps like Word and OneNote.

Correct answer & explanation
✓
Word for the web
Word for the web and OneNote for the web are both part of the Microsoft 365 web apps suite that support real-time co-authoring. They leverage the Office Online Server infrastructure and the Fluid Framework to allow multiple users to edit the same document simultaneously, with changes syncing via WebSocket connections and operational transforms.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Microsoft Teams
Why it's wrong here
Microsoft Teams is a collaboration hub centered on persistent chat, meetings, and channels, not a document authoring surface. While team members can share, upload, and launch Word/Excel/PowerPoint files via the Files tab and co-author them in embedded Office web apps, Teams itself does not provide native creation or editing of document content. Thus, Teams facilitates the workflow, but the actual creation and editing occurs in the Office for the web apps.
- ✗
Outlook on the web
Why it's wrong here
Outlook on the web is a mail, calendar, and contacts client; its composer creates email messages rather than editable documents. Users can attach files or open attachments in their associated Office for the web app, but Outlook itself provides no document canvas for content creation or collaborative editing. Consequently, it is not an app used to create and edit documents.
- ✗
Access for the web
Why it's wrong here
Access for the web is a relational database application for building tables, queries, forms, and reports, not a general-purpose document editor. Its web version focuses on data entry and business-app logic, and although it allows some object customization, it does not support real-time co-authoring of narrative or formatted documents. Therefore, it does not fit the 'create and edit documents' scenario.
- ✓
Word for the web
Why this is correct
Word for the web is a full browser-based word processor that lets users create, format, and edit .docx documents with real-time co-authoring, comment mentions, and autosave. Multiple authors can view edits by other users within seconds, with version history accessible through the ribbon's File menu. Because it provides the core Office editing experience plus live collaboration, it is one of the two correct answers.
- ✓
OneNote for the web
Why this is correct
OneNote for the web is a digital notebook that supports real-time shared note-taking, allowing multiple users to add, edit, and organize text, images, and handwriting simultaneously. Unlike Word, its canvas is free-form and not tied to a paginated document, yet it still qualifies as creating and editing digital content in Microsoft 365. The real-time sync and collaborative editing make it the second correct answer.
