MC280287 – Updated September 23, 2021: Reminder to update Microsoft To Do apps (Android, iOS, Windows and Mac) and Outlook apps(Android and iOS) to the latest available version before October 31, 2021

If your organization does not use Microsoft To Do, you can disregard this message. 

Microsoft is moving Microsoft To Do’s backend to a more efficient service. For the best experience across all of your devices, you need to update to the latest version. Make sure your mobile and desktop To Do apps are version 2.49 or higher before end of October 2021 to avoid any issues with cross device syncing. Also since To Do tasks are also linked with Outlook Android and iOS apps. Please make sure that you update your Outlook android and iOS apps as well.

Key points

• Timing: Before October 31, 2021
• Roll-out: tenant level
• Action: Update Microsoft To Do apps (Android, iOS, Windows and Mac) and Outlook apps(Android and iOS) to the latest available version before October 31, 2021.

How this will affect your organization:

After October 2021, To Do app versions 2.48 or below will no longer sync across devices, but you’ll still be able to use To Do in offline mode. After October 2021, you can keep your To Do apps syncing by updating your apps to the latest version. If you log out before updating to version 2.49 or higher, you will lose all un-synced data.

What you need to do to prepare:

Please make sure you update your To Do apps(Android, iOS, Windows and Mac) and Outlook apps(Android and iOS) to the latest available version before 31st October 2021. Update your To Do apps to the latest version in the appropriate app store.
