Question 77 of 217
MS-900 Describe Microsoft 365 apps and services Practice Question
A project team needs to create a shared workspace to manage tasks, share files, track project milestones, and communicate through conversation threads. They want a single app that integrates with other Microsoft 365 services like Outlook and Teams. Which Microsoft 365 app is best suited for this requirement?
⚠ Common exam trap
Many candidates confuse Microsoft To Do as a team tool because of its integration with Outlook tasks, but it lacks shared workspaces and team collaboration features, which are core to Planner.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Microsoft Planner
Microsoft Planner is best suited because it provides a shared workspace with buckets and cards for task management, file attachments, milestone tracking via checklists and due dates, and conversation threads on each task. It integrates natively with Outlook for task visibility and with Teams via the Planner tab, meeting the requirement for a single app that combines these capabilities.
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 Planner
Why this is correct
Microsoft Planner is correct because it provides a shared Kanban-style task board within Microsoft 365, where team members can create buckets, assign tasks, set due dates, attach files, and add checklists. Each task includes a comments section for threaded, collaborative conversations, and the board offers real-time progress charts. Planner integrates natively as a tab in Microsoft Teams and syncs with Outlook tasks, making it purpose-built for lightweight team project management and milestone tracking.
- ✗
Microsoft To Do
Why it's wrong here
Microsoft To Do is incorrect for this scenario because it is designed primarily for personal task management, not for team collaboration. While you can create multiple lists and set reminders, a To Do list cannot be shared as a shared workspace with multiple editors, and it lacks threaded conversation threads, file attachment collaboration, and milestone tracking. Tasks assigned to you from Planner may appear in To Do, but To Do itself does not provide the shared board and communication hub required by the project team.
- ✗
Microsoft Project for the web
Why it's wrong here
Microsoft Project for the web is designed for formal project scheduling, resource allocation, and Gantt-chart-based planning, not for providing a shared workspace with integrated task management, file sharing, milestone tracking, and threaded conversations. It lacks the persistent conversation threads and file-sharing hub that the scenario demands. It is tempting because its name suggests project management, and it would be correct for a team needing detailed schedule and resource management, but it does not replace a collaborative workspace app like Microsoft Teams.
- ✗
Microsoft Lists
Why it's wrong here
Microsoft Lists is incorrect because it is optimized for tracking structured information in a list format, such as inventory, contacts, or issue trackers, using custom columns, views, and formatting. Although list items support comments and attachments, Lists does not offer a Kanban task board with assignable task cards, due-date-driven milestone management, or persistent team conversation threads like a dedicated collaborative workspace. It is a data-collection and tracking tool, not a task-management and team-communication hub.
