Question details

The user needs to recover Microsoft To Do lists and tasks that were inadvertently deleted when clearing synchronized content from the Apple iPhone Reminders app.

Product: Microsoft To Do
Device & OS: iOS
Scenario: Accidental deletion of tasks on an iPhone caused the linked Microsoft To Do data to be wiped out across the ecosystem.
Observed behavior: Deleting items in the iPhone Reminders app automatically removes the corresponding Microsoft To Do lists, leaving the user with limited recovery options.

Before you start

Turn off Wi-Fi and Cellular Data on your iPhone immediately to prevent the device from syncing the deletion to the cloud and overwriting your remaining data backups.

Solution 1Recommended

Check Outlook Deleted Items and OneDrive Recycle Bin

Because Microsoft To Do synchronizes via Microsoft Exchange, deleted tasks are frequently moved to your Outlook email's Deleted Items folder rather than being permanently destroyed.

This is the safest and least disruptive method to recover your tasks. If the lists were saved as files or connected to Microsoft 365, they might also appear in the OneDrive Recycle bin.

Log into Outlook Web

Open a web browser and sign in to Outlook.com using the Microsoft account associated with your Microsoft To Do app.

Access the Deleted Items folder

On the left-hand navigation pane, click on the 'Deleted Items' folder.

Restore the Tasks

Search for your deleted tasks in the list. If you find them, right-click on the items, select 'Move', and choose 'Tasks' to restore them to your Microsoft To Do account.

Check OneDrive Recycle Bin

If you cannot find them in Outlook, log into OneDrive.com, navigate to the 'Recycle bin' on the left panel, and look for any deleted task lists or associated files to restore.

Solution 2

Restore iPhone from an iCloud Backup

If the data is completely erased from Microsoft's servers, you can revert your iPhone to a previous iCloud backup taken before the deletion occurred.

Frequently Asked Questions

Why did deleting an Apple Reminder delete my Microsoft To Do task?

If you added your Microsoft Outlook/Exchange account to your iPhone's Accounts settings and enabled 'Reminders' syncing, the two apps mirror each other. Deleting a task in Apple Reminders sends a command to delete it from Microsoft To Do as well.

Can I recover Microsoft To Do tasks from the iPhone 'Recently Deleted' folder?

No. Apple Reminders does not feature a 'Recently Deleted' folder for individual tasks. When a synced task is deleted, it bypasses local trash and is immediately removed from the active server.

How do I stop Apple Reminders from syncing with Microsoft To Do?

To prevent future sync conflicts, navigate to your iPhone Settings, tap 'Mail' (or 'Passwords & Accounts' depending on your iOS version), select your Microsoft/Outlook account, and toggle off the switch for 'Reminders'.
