How do I fix Microsoft to do

Question

Hello,
My personal Microsoft account’s To Do is still running on the old backend (to-do.live.com). The app shows version 2.129.5 and does not match the new To Do experience my work account uses.

Because of this, I am experiencing multiple issues:
- Tasks and lists do not delete reliably
- Tasks reappear after deletion
- Lists behave inconsistently
- Sync is unreliable
- Features available in the new To Do backend are missing

On the same device, my work Microsoft account works perfectly in the new To Do environment, so this appears to be an account-level backend issue, not a device issue.

Could you please migrate my personal Microsoft account to the new To Do backend or reset my To Do data on the server side?

Thank you.

Answer 1

What is it going to take for Microsoft to do the following - Support can then check the account’s To Do service state and perform any necessary back end corrections.

Answer 2

I have tried all of this, and it still does not work. the response that I originally provided came from copilot. it appears Microsoft refuses to look at what is happening on the back end.

Answer 3

The backend used by Microsoft To Do for a specific personal account cannot be changed or migrated manually. When To Do behaves inconsistently for a given account (tasks not deleting, items reappearing, sync issues), the supported options are:

1. Confirm app version and update

• Ensure the To Do app is updated to at least version 2.60 or higher on all devices.
• Update from the appropriate store:
  • Microsoft Store (Windows)
  • Mac App Store (macOS)
  • iOS App Store (iOS)
  • Google Play Store (Android)
• Using an outdated client can cause sync and cross-device issues.

2. Check for local storage corruption (Mac/iOS) If using To Do on Mac or iOS and seeing sync failures or inconsistent behavior, clear the local database and reinstall:

• Mac:
  1. Uninstall the To Do app.
  2. Open Finder.
  3. Press CMD+Shift+G and go to: ~/Library/Group Containers/UBF8T346G9.com.microsoft.to-do-mac/AccountData/userdatabase.db
  4. Delete userdatabase.db.
  5. Reinstall To Do from the Mac App Store.
• iOS:
  • Uninstall and reinstall the To Do app from the App Store.

3. Ensure the account is supported

• To Do requires an Exchange Online mailbox for storage and sync. If the account does not have a supported Exchange Online mailbox type, To Do features and sync will not work correctly.
• Supported plans include: Exchange Essentials, Exchange Online Kiosk, Exchange Online Plan 1, Exchange Online (Plan 1), Exchange Online (Plan 2), Exchange Online (P1), and Exchange Online POP.
• On-premises-only Exchange accounts are not supported.

4. Do not sign out until data is synced

• If the app is in an out-of-date or error state, signing out before sync completes can cause data loss. Update the app first and allow it to sync before considering sign-out.

5. Contact in-app support for account-level issues Because backend and account migrations cannot be performed by end users, any required server-side reset or backend correction must be handled by Microsoft support:

• On iOS/Android:
  1. Open To Do.
  2. Tap the username to open account settings.
  3. Go to Help & Feedback > Get support.
  4. Use in-app messaging (top-right) to contact support and describe that the personal account is still on the old backend and experiencing sync/deletion issues.
• On Windows/Web:
  1. Select the username in To Do.
  2. Choose Help & Feedback > Get support.
  3. Use the in-app messaging option to reach support and request investigation/reset of To Do data for the personal account.

Provide details such as:

• The affected personal Microsoft account (do not share passwords).
• That the app is on version 2.129.5 or later.
• The symptoms (tasks reappearing, lists not deleting, sync issues).
• That the work account on the same device works correctly.

Support can then check the account’s To Do service state and perform any necessary backend corrections.
