MS-900 Describe Microsoft 365 apps and services Practice Question
A project manager wants a shared workspace where team members can create and track tasks, set deadlines, and collaborate on documents. This workspace should integrate with Microsoft Teams for quick access. Which Microsoft 365 service is best suited for this purpose?
⚠ Common exam trap
A common mix-up: candidates confuse Microsoft Lists with Planner because both involve tracking items, but Lists is for static data collection (like a spreadsheet) while Planner is for dynamic task management with assignments and deadlines.

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 the correct choice because it provides a shared workspace (Plan) where team members can create and track tasks, set deadlines, and collaborate on documents. It integrates natively with Microsoft Teams via the Planner tab, allowing quick access within a Teams channel, and supports file attachments from SharePoint/OneDrive for collaboration.
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 Lists
Why it's wrong here
Microsoft Lists is a data-tracking app for capturing structured information like issue trackers or inventories, with customizable columns, views, and conditional formatting. Although a list can include a 'Task' column and be added to Teams, it does not provide out-of-the-box task assignment, due-date reminders, or an interactive board with drag-and-drop progress states, so it is not a shared task workspace. Teams need Planner for collaborative work management.
- ✓
Microsoft Planner
Why this is correct
Microsoft Planner is a collaborative task management tool built around a visual Kanban board where each task has assignees, due dates, checklists, labels, and file attachments. Every Planner plan is backed by a Microsoft 365 Group, giving the team a shared mailbox, calendar, and SharePoint document library for co-authoring, and the Board can be embedded into Teams as a tab. Its simplicity and native Teams integration make it the correct choice for a shared workspace with assignments and deadlines.
- ✗
Microsoft To Do
Why it's wrong here
Microsoft To Do is a personal productivity app focused on individual task lists, with features like My Day, reminders, and integration with Outlook tasks. While it can aggregate Planner tasks assigned to you via 'Assigned to me,' it does not allow multiple users to co-manage a shared list or assign work to others, so it cannot act as a team workspace. For a project manager, To Do offers no board views, no team-wide progress charts, and no shared file repository, making it unsuitable for collaboration.
- ✗
Microsoft Project Online
Why it's wrong here
Microsoft Project Online is designed for advanced portfolio management and scheduling, not for lightweight team task tracking with document collaboration. It lacks native integration with Microsoft Teams for quick access and does not provide a shared workspace for real-time document co-authoring. The option tempts because its name suggests project management; it would be correct for a scenario requiring Gantt charts, resource levelling, and critical path analysis across multiple projects.
