Is there a native Todoist Microsoft To Do integration?

There is not a simple native first-party sync that makes Todoist and Microsoft To Do behave like one app. Most setups use an automation tool or choose one app as the source of truth.

Will my due dates and reminders carry over?

Due dates can often be mapped. Reminders, subtasks, labels, priorities, and project structure are less reliable because the apps model tasks differently.

Can I sync in both directions?

You can build two-way automations, but they are easy to break. One-way sync from a chosen source of truth is usually safer.

Do subtasks and labels survive the trip?

Often not cleanly. Subtasks, labels, sections, and priorities may flatten, move into notes, or get dropped. Test before trusting the integration.

Todoist Microsoft To Do Integration: What Actually Works

Quick answer: Todoist and Microsoft To Do do not have a simple native sync that makes them behave like one shared task app. The practical options are one-way automation, carefully built two-way automation, or choosing one app as the source of truth and keeping the other for a specific workflow.

Why this integration is messy

Todoist and Microsoft To Do both manage tasks, but they do not organize them the same way.

Todoist has projects, labels, filters, priorities, natural-language scheduling, and strong personal productivity workflows.

Microsoft To Do is tied into Microsoft 365, Outlook flagged emails, Teams context, and work accounts.

The overlap is obvious. The data model is not identical. That is why a perfect sync is harder than it looks.

Your realistic options

Option	Best for	Risk
Use one app only	Cleanest workflow	Giving up features from the other app
One-way automation	Moving tasks from source to destination	Missing completion/status updates
Two-way automation	Keeping both apps active	Duplicates and sync loops
Manual weekly review	Low-volume task transfer	Easy to forget

Most people should choose one source of truth. If you think in Todoist, let Todoist own your tasks. If your work runs through Microsoft, let To Do own work tasks.

Build a one-way automation

Use an automation tool such as Zapier, Make, Power Automate, or another connector that supports both systems.

Choose the source app.

Choose the trigger, such as “new task” or “new task in project/list.”

Choose the destination app.

Create the matching task.

Map fields carefully.

Test with one disposable task.

Then test a task with a due date, a note, and a reminder before trusting the automation.

One-way sync is usually safer because it avoids loops. A Todoist task can create a Microsoft To Do task, but the copied To Do task does not create another Todoist task in return.

What usually maps well

Field	Reliability
Task title	High
Due date	Medium-high
Notes/description	Medium
Completion status	Medium, if explicitly automated
Assignee	Low-medium, depends on account/tool

The title is the safest field. If a detail is critical, put it in the title or first line of the note.

What often breaks

Feature	Why it breaks
Subtasks	Apps store hierarchy differently.
Labels/tags	Todoist labels do not map neatly to Microsoft To Do.
Projects/sections	Destination lists may not match source projects.
Reminders	Reminder models and notifications differ.
Priorities	Priority systems may not translate.
Recurring tasks	Recurrence rules can behave differently.

Do not assume a complex Todoist project will become a clean Microsoft To Do list.

Two-way sync warning

Two-way sync sounds better than one-way sync until it duplicates everything.

A common loop:

Todoist task is created.
Automation creates a Microsoft To Do task.
Second automation sees the Microsoft To Do task as new.
It creates another Todoist task.
The loop continues or creates confusing duplicates.

If you build two-way sync, use filters, tags, or dedicated lists so copied tasks are not treated as new source tasks.

Better workflow patterns

Use Todoist for personal planning and Microsoft To Do for work tasks from Outlook.

Use Microsoft To Do as the work capture inbox, then manually move selected tasks into Todoist during daily planning.

Use Todoist as the source of truth and push only scheduled work tasks into Microsoft To Do.

Use calendar time blocking instead of trying to maintain two identical task lists. For that route, see Todoist Google Calendar integration and weekly time block planning.

Troubleshooting

Problem	Likely cause	Fix
Duplicate tasks	Two-way automation loop	Add filters or switch to one-way sync.
Due dates missing	Field not mapped	Edit the automation mapping.
Reminders missing	Apps handle reminders differently	Set reminders in the app that will notify you.
Subtasks lost	Hierarchy unsupported	Flatten important steps into the note.
Completed tasks stay open	Completion sync was not automated	Add a separate completion rule or complete in source app only.
Work account blocks connector	Microsoft admin policy	Ask IT or use manual review.

LifeLoad angle

Syncing task apps can help, but it can also become another maintenance job.

The deeper question is whether your tasks fit your calendar and energy. LifeLoad is built around that load question. Before perfecting a Todoist-to-Microsoft-To-Do bridge, decide which app you actually trust and how those tasks become time on the calendar.
