Summary
Microsoft 365 includes three different task management tools — Microsoft To Do, Microsoft Planner, and Microsoft Lists — and it is not always obvious which one to use. All three track "things to do," but they are designed for very different scenarios. This article is a decision guide that compares the three tools side by side so you can pick the right one for your workflow.
Prerequisites
- A Microsoft 365 work or school account.
- All three apps are included in most Microsoft 365 plans — no additional license required.
- Access via web (office.com), desktop apps, mobile apps, or Teams.

3. Detailed Breakdown — When to Use Each Tool
Microsoft To Do — Your Personal Productivity Hub
Best for: Individual tasks, daily planning, and personal accountability.
- My Day — A daily planning view where you pick which tasks to focus on today. Resets each morning.
- Flagged Emails — Any email you flag in Outlook automatically appears as a To Do task.
- Steps — Break a task into subtasks (steps) and check them off as you go.
- Lists — Organize tasks into separate lists (e.g., "Work," "Personal," "Project X").
- Sync — Tasks sync across the To Do app (web, desktop, mobile) and Outlook.
Do not use To Do for: Team projects where multiple people need assignments and visibility into each other's work.
Microsoft Planner — Team Task Management Made Simple
Best for: Team projects where tasks are assigned to people, tracked on a board, and tied to deadlines.
- Buckets — Organize tasks into columns (buckets) like "To Do," "In Progress," and "Done."
- Board view — Drag-and-drop Kanban board for visual task tracking.
- Charts — Built-in dashboard showing task progress, workload by member, and priority breakdown.
- Schedule — Calendar view showing tasks by due date.
- Teams integration — Add a Planner tab to any Teams channel for seamless access.
- Assignments — Assign tasks to one or more team members with due dates and priority.
Do not use Planner for: Tracking data that has many custom fields (use Lists instead) or personal tasks (use To Do instead).
Microsoft Lists — Structured Data and Workflow Tracking
Best for: Tracking structured information that goes beyond simple tasks — issues, requests, inventories, project logs.
- Custom columns — Add any type of field: text, number, date, choice, person, yes/no, hyperlink, image, calculated.
- Multiple views — Grid (spreadsheet-like), Board (Kanban), Gallery (card), Calendar.
- Rules — Built-in automation: send notifications, set field values, or move items when conditions are met.
- Power Automate integration — Trigger advanced workflows when items are created or updated.
- Templates — Start from pre-built templates (Issue Tracker, Event Itinerary, Content Scheduler, etc.).
- SharePoint foundation — Lists are stored in SharePoint, so they inherit permissions, versioning, and search.
Do not use Lists for: Simple personal to-do items (use To Do) or team tasks that need assignment and a board view (use Planner).
4. Decision Matrix — Choosing the Right Tool
| Decision Factor | To Do | Planner | Lists |
|---|---|---|---|
| Number of users | 1 (you) | 2–50 (a team) | 2–unlimited (a team or department) |
| Task complexity | Simple (title + due date + steps) | Moderate (assignment + priority + checklist) | Complex (custom fields, views, automation) |
| Need for custom fields | ❌ No | ❌ No | ✅ Yes — fully customizable |
| Need for automation | ❌ No | ⚠️ Basic notifications only | ✅ Yes — rules + Power Automate |
| Need for a Kanban board | ❌ No | ✅ Yes — primary view | ✅ Yes — Board view available |
| Need for recurring tasks | ✅ Yes | ❌ No | ❌ No (use Power Automate) |
| Need for Outlook integration | ✅ Flagged emails sync automatically | ⚠️ Calendar view only | ❌ No |
| Data lives in | Your mailbox | M365 Group (SharePoint) | SharePoint site |
5. Can They Work Together?
Yes. The three tools complement each other:
- To Do + Planner: Tasks assigned to you in Planner automatically appear in your To Do app under Assigned to me. You manage your daily focus in To Do while the team tracks progress in Planner.
- Planner + Lists: Use Planner for team task tracking and Lists for structured data tracking (e.g., an issue log or asset inventory). Link them in the same Teams channel.
- Lists + Power Automate: Automate list updates — for example, when a status changes to "Approved," send an email and create a Planner task automatically.
Tip: In Teams, you can add both a Planner tab and a Lists tab to the same channel, giving your team a task board and a data tracker side by side.

Troubleshooting
INFO
If you cannot find one of these apps, it may be disabled by your organization's IT policies. Contact IT to check whether the app is enabled for your account.

| Cannot create a new Plan | No Microsoft 365 Group available | Planner requires a Microsoft 365 Group. Create a new Group or Team, and the Plan will be created automatically. |
| Lists app not available in Teams | App disabled by admin | Contact IT to enable the Lists app in your organization's Teams app policies. |
| Cannot assign tasks in Planner to someone | Person not in the Microsoft 365 Group | Add them to the Group or Teams team first, then assign the task. |
| Flagged emails not appearing in To Do | Exchange sync issue | Open To Do on the web (to-do.office.com) and check the Flagged Emails list. If empty, try unflagging and re-flagging an email. |
| Custom columns missing in Lists | Using a template that does not include them | Edit the list settings → Add column to create custom fields. Templates are starting points — you can always customize them. |
| Cannot delete a Plan | Only Group owners can delete Plans | Contact the Team/Group owner or your IT department. Plans can be deleted from Planner settings or by deleting the Group. |
