Supported accounts

Microsoft To-Do is free when you use your personal Microsoft Account, which means Microsoft To-Do is available to all Office 365 Home and Personal customers as well. Both free and Office 365-subscribed personal Microsoft Accounts rely on Exchange Online servers, so the technical requirements detailed below are met by default.

Common examples of personal Microsoft Accounts are what you use to log in to Skype, Outlook.com or Xbox. You can manage your personal Microsoft Account here: https://account.microsoft.com  

You can also use a work or school Microsoft Account, but you'll want to make sure it is supported first. The following Office 365 suites include the licenses needed to use Microsoft To-Do with a work or school account:  

  • Business Essentials

  • Business Premium

  • Microsoft 365 Firstline F1

  • Enterprise Firstline F1-F2

  • Enterprise E1-E5

  • Secure Productive Business

  • Secure Productive Enterprise E3

  • Secure Productive Enterprise E5

  • Education E1-E5

  • Education A1-A5

  • Microsoft 365 A3-A5

In addition to a valid product license, one of the following versions of Exchange Online is needed for To-Do to be able to sync user data: 

  • Exchange Online (Plan 1)

  • Exchange Online (Plan 2)

  • Exchange Essentials

  • Exchange Online Kiosk

  • Exchange Online Plan 1
