Microsoft To Do is a task manager for work and personal to-dos. Users organise tasks in lists, plan their day in a My Day view, set due dates and reminders, add steps and notes, and share lists with others. It runs on the web and on Windows, Mac, iOS and Android. Tasks are stored on Exchange Online, so they also appear in Outlook tasks.
Microsoft To Do is published by Microsoft Corporation in Redmond, Washington, United States. For customers in the EEA, the UK and Switzerland, Microsoft Ireland Operations Limited is the data controller. Microsoft's privacy statement says personal data is stored primarily in the user's region or in the United States. For Microsoft 365 business tenants with an EU or EFTA sign-up location, the EU Data Boundary commits storage and processing to datacentres in those areas. The boundary documentation does not name To Do explicitly, and consumer accounts are not covered. A European organisation therefore relies on a US provider's terms and should check the scope for its own account type.
