Set up Microsoft To Do with one Microsoft account you can use on every device, install the app on your main device plus the web version, and create a small starter structure such as Work, Personal, and Next Actions. If you choose the wrong account or skip sync checks, tasks can split across accounts and vanish from the view you expect. This guide covers the fastest setup path for web, Windows, iPhone, Android, and work accounts, plus the first list structure and a quick sync check.
What you’ll need
- A Microsoft account you can keep using on every device you want synced.
- A browser, Windows device, iPhone/iPad, or Android device.
- An internet connection for the first sign-in and sync.
- If you want Outlook tasks from day one, access to the same work or school account in Outlook and Microsoft To Do.

How to set up Microsoft To Do for the first time
Start with one Microsoft account and one simple list structure. Open Microsoft To Do on the web or on your main device, sign in, then confirm that the same account appears everywhere before you add tasks. If you want Outlook tasks, connect that account at the start so flagged email and tasks land in one place.
1. Pick one Microsoft account
- Choose the Microsoft account you want to use for your tasks.
- Use that same account on every device you want synced.
- If you have both personal and work accounts, decide now which one owns your main task lists.
2. Choose your first app path
- Open the web app in a browser, or install the desktop or mobile app on your main device.
- For Windows work setups, install Microsoft To Do directly from the Microsoft Store or use the web version in a browser.
- For iPhone/iPad or Android, install the mobile app and sign in right away.
3. Decide on Outlook tasks before adding anything
- If you want flagged mail to show up as tasks, use the same account in Outlook and To Do.
- Open Outlook and confirm the account you use for mail.
- Then open To Do and sign in with that same account.
4. Build your first list structure
- Create starter lists that fit your workflow.
- Put only current tasks in Next Actions.
- Use My Day as your daily view, not as your only storage place.
Say your work laptop uses a school account and your phone uses a personal account. Tasks added on the phone will not appear on the laptop if the account differs, even though both devices are signed in.
If you want a daily planning habit, put today’s tasks into My Day each morning, then move unfinished items back to a broader list at the end of the day. That keeps the daily view simple and keeps older tasks in the right place.
Set up Microsoft To Do on the web
The web app is the quickest setup path if you do not want to install anything. Open To Do in a browser, sign in with your Microsoft account, and wait for the first sync to finish before adding tasks. Use the same account in every browser session if you want the same lists everywhere.
Open the browser app
- Open your browser and go to https://todo.microsoft.com/.
- Sign in with your Microsoft account.
- Wait for your lists to load before you create anything new.
Confirm the right account and sync
- Open the account menu in To Do.
- Check the email address shown there.
- Refresh the page and confirm the same lists appear again after reload.
Set up Microsoft to do on windows, iPhone, or Android
Windows users can install the desktop app from the Microsoft Store or open the web version in a browser. iPhone/iPad and Android users should install the mobile app, then sign in with the same Microsoft account used on the web or desktop. Match the account before you start any list work.
Windows desktop
- Open Microsoft Store and install Microsoft To Do, or open the web version in your browser.
- Sign in with the account you want to use.
- Check that the signed-in email matches your web account.
iPhone or iPad
- Install Microsoft To Do from the iOS app store.
- Open the app and sign in with the same Microsoft account.
- Confirm that the same lists from the web appear on the device.
Android
- Install Microsoft To Do from Google Play.
- Sign in with the same Microsoft account you used on the web or Windows.
- Check that list names and task counts match the other device.
Build your first list structure
Keep the first structure small and easy to maintain. A single personal list is enough if you want the simplest setup, but a common setup for many new users is 3 starter lists: Work, Personal, and Next Actions. Use My Day for what you will do today, while the main lists hold the larger task pool.
Use My Day as a planning view
- Open My Day each morning.
- Add only the tasks you want to complete today.
- Review it again in the evening and move unfinished items back to a main list if needed.
Add due dates, steps, and reminders only where needed
- Open one task and add a due date only if timing matters.
- Add steps when a task needs a clear sequence.
- Set a reminder only when you need a timed prompt.

| Device | App path | Account to use | What to click next | Verification step |
|---|---|---|---|---|
| Web | Browser-based Microsoft To Do web app | The Microsoft account you want synced everywhere | Sign in, then open My Day and your lists | Refresh the page and confirm the same lists reappear |
| Windows desktop | Microsoft 365 apps, then Microsoft To Do | The same personal, work, or school account used on the web | Open To Do from the desktop app path and sign in | Check that the account email matches the web version |
| iPhone/iPad | Install the Microsoft To Do iOS app | The same Microsoft account used on web or Windows | Open the app and allow sign-in | Confirm that your starter lists appear |
| Android | Install the Microsoft To Do Android app | The same Microsoft account used on the other devices | Open the app and sign in | Check that task counts match the other device |
| Outlook integration | Outlook tasks connected to Microsoft To Do | The same Outlook account and Microsoft To Do account | Use the same sign-in in Outlook, then open To Do | Verify flagged items appear in the Tasks view |
Common mistakes to avoid
Most setup problems come from account mismatch, not from the app itself. If your personal account is signed into To Do on your phone and your work account is signed in on Windows, your lists will not match. The other common issue is opening the app but never completing sign-in.
- Do not mix personal and work accounts unless you want separate task spaces.
- Do not assume installation completes setup; sign in after install.
- Do not expect Outlook items to appear unless the Outlook account matches the To Do account.
- Do not build a large list before confirming sync on the first two devices.
A common first-timer mistake is adding 20 tasks on a phone before checking the Windows sign-in. If the phone used a different account, those tasks will stay attached to that account and seem to disappear elsewhere.
Frequently asked questions
How do I set up Microsoft To Do for the first time?
Open To Do on the web or in the app, sign in with one Microsoft account, then create a small first structure: Work, Personal, and Next Actions. Check that the same account shows on every device before you add tasks, because account mismatches are the fastest way to split lists.
How do I install Microsoft to Do on Windows or Mac?
On Windows, install Microsoft To Do from the Microsoft Store or open the web version in a browser. On Mac, use the Microsoft To Do app or the web version in a browser.
How do I sign in to Microsoft To Do with my Microsoft account?
Open the app or web version, choose Sign in, and enter the Microsoft account you want synced. If you use both personal and work accounts, check the email address after sign-in. That one choice controls which tasks appear on each device.
How do I sync Microsoft To Do across my phone and PC?
Use the same Microsoft account on both devices, then let the first sync finish before you create new lists. Open To Do on the web, Windows, iPhone/iPad, or Android and confirm the list names match. If they do not, the account is different.
How do I set up Microsoft To Do with Outlook tasks?
Sign in to Outlook and Microsoft To Do with the same account, then flag an email in Outlook and open Flagged Email in To Do. The flagged item should appear there. If it does not, the accounts do not match or the sync has not completed yet.
Can I use Microsoft to do without the Microsoft store?
Yes. Use the web app in a browser if you do not want the Microsoft Store route on Windows. That path still lets you sign in, sync lists, and check the same account on your phone and PC without adding a store install step.
