A cloud-based task management app from Microsoft that helps users organize and manage daily tasks across devices.
First, open Microsoft To Do on the web using the same Microsoft account as the phone; if the list is absent there too, check Outlook’s Deleted Items and restore the list to Tasks.
1. Check whether the list still exists online
- On the phone, open Microsoft To Do → Settings and note the signed-in email address.
- In a browser, open https://to-do.microsoft.com and sign in with that exact account.
- Check the complete list menu—not only My Day or another filtered view.
Microsoft To Do requires the same account on both devices and normally synchronizes lists automatically. ^1^
- List appears on the web: The data is intact, and the phone has a local display or synchronization problem. Pull down in the phone app to refresh, then sign out and back in using the same account.
- List is also missing on the web: Continue with recovery below.
2. Restore the list from Outlook
Microsoft To Do lists are stored in Exchange Online and can be recovered through Outlook if accidentally deleted:
- Open Outlook desktop and sign in with the same Microsoft account used in To Do.
- In the mail folder list, select Deleted Items.
- Find the folder with the missing To Do list’s name.
- Right-click it and select Move → Other Folder → Tasks.
- Reopen or refresh Microsoft To Do and allow time for the restored list to synchronize. ^2^
If it still cannot be found
- Check whether another personal, work, or school account was used when the list was created.
- If To Do displays a firewall, 503, local-storage, or synchronization error, follow the fix for that specific message. VPNs, proxies, and corporate firewall restrictions can prevent synchronization. ^3^
- For a work or school account, ask the Microsoft 365 administrator to check for a service or account issue.
- Avoid creating a replacement list with the same name until the web and Deleted Items checks are complete, so the original and replacement are not confused.
