Microsoft To-Do and Cortana integration

Microsoft To-Do helps you manage, prioritize, and complete the most important things you need to achieve each day, powered by Office 365 integration.

Now, with Cortana integration, you can save time and stay organized. Cortana helps by adding your reminders and tasks to your lists in Microsoft To-Do, so you can stay on top of what matters most. Use your voice, your PC, your phone—your choice.

Streamline your tasks. Your lists and reminders from across Microsoft To-Do, Cortana, and tasks in Outlook can now become one, centrally located in your Microsoft To-Do app. Use Microsoft To-Do anywhere: on your Android or iPhone, with Cortana, or on your Windows 10 PC. You can also access Microsoft To-Do online. It’s automatically synced too, so you never miss a beat.

Getting started

Your Windows 10 PC must be running Windows 10 Insider Preview Build 18267+ and be tied to either the Australia, India, US, or UK region. To sync your reminders and lists across Cortana, Microsoft To-Do, and Outlook, set up Outlook or Office 365 as a connected service in Cortana on your PC.

  1. Go to Cortana > Notebook > Manage Skills > Connected services.
  2. Select your account type:
    1. For a personal Microsoft account, select Outlook.
    2. For an enterprise account, select Office 365.
  3. Connect.
  4. Your reminders and lists across Cortana, Microsoft To-Do, and Outlook will now start syncing.

Example of reminders and lists in Cortana, Microsoft To-Do and Outlook.

If you already have Outlook or Office 365 set up as a connected service in Cortana:

  1. Start syncing reminders from Cortana > Notebook > Organizer > Reminders.
  2. Or start syncing lists from Cortana > Notebook > Organizer > Lists.

Then, sign in to the Microsoft To-Do app or Outlook with the same personal or enterprise account you used earlier, when setting up connected services in Cortana. All your reminders and lists will now be synced across Cortana, Microsoft To-Do, and Outlook.

Things to try

Add items to a list

  1. Open the Microsoft To-Do app on your PC and create a new list titled “Travel”.
  2. Ask Cortana to add “Paris” to your “Travel” list.
  3. Verify if “Paris” was automatically added to your “Travel” list on Microsoft To-Do.
  4. Your accounts should sync automatically. If you need to force a sync, go to the Microsoft To-Do app, select your account name, and choose Settings > Sync.

Set reminders

  1. Ask Cortana, “Remind me to call Dave in 2 minutes.”
  2. Wait for the reminder. You should receive a Microsoft To-Do reminder and a Cortana reminder.
  3. Reminders should appear in both your Microsoft To-Do planned tasks and your Cortana To-Do lists.
  4. In the Microsoft To-Do app and Cortana, you can also add a time reminder on any item in the lists.

Recall items on a list

  1. Ask Cortana, “What’s on my To-Do list?”
  2. Try this with any other named lists, like “What’s on my Grocery list?”

Recall your reminders

  1. Go to the Microsoft To-Do app and select Tasks.
  2. Create a new task and add it to the Task list.
  3. Select the new task to edit.
  4. Select Remind me and set a reminder for later in the day.
  5. Ask Cortana, “What are my reminders for today?”
  6. Try with other things, like “What are my reminders in the evening?”

Tips and troubleshooting

[UPDATED 1/26] While we are continuously working to improve and deepen our Cortana integration, we are aware of some current limitations:

  • It works best when you disconnect Wunderlist from Cortana.
  • Try disconnecting and setting up Outlook or Office 365 connected service again if reminders and lists do not sync across Cortana, Microsoft To-Do, and Outlook even after performing the steps described above.
  • Location-based reminders can only be created in Cortana, but you can view them in your Microsoft To-Do app.
  • Attachments added with Cortana are only accessible in Cortana. They won’t sync to Microsoft To-Do.
  • A list shared between multiple people in the Microsoft To-Do app will only appear in Cortana for the person who shared it. All members of the list can still access the list in Microsoft To-Do.
  • You may see duplicate notifications from Cortana, Microsoft To-Do, and Outlook apps on your Windows 10 PC or iOS phone for a single reminder. Learn how to change notification settings in Windows 10.
  • You may see the Reminders app on iPhone triggering reminders set in Cortana. This typically happens if the reminders sync is turned on in Settings > Passwords and Accounts > Outlook. Turn off reminders sync to prevent the Reminder app from triggering Cortana reminders.
