I have 2 lists tens of tasks sorted into them. while navigating between them, suddenly all of them have disappeared except for one task and flagged emails. Is there any troubleshooting or recovery I should do?

    Hi Mohannad Abdelsalam

    You can try to:

    Check the account you're signed in with: If you have multiple Microsoft 365 accounts, verify that you're signed into the correct work account where the lists were created.

    Check Microsoft To Do on another platform

    Force a sync

    • Sign out of Microsoft To Do and sign back in, ensure the device has a stable internet connection and allow the app to complete synchronization.

    Check whether the lists were accidentally deleted

    • Personal task lists deleted from To Do generally cannot be restored by end users. However, if the tasks were associated with Outlook Tasks, check the Deleted Items folder in Outlook for any recoverable task items.

    If the lists are missing in both Microsoft To Do and Outlook on the web, to better understand you situation, could you please share some information:

    • Approximately when the lists disappeared.
    • Whether all tasks are missing or only the custom lists.
    • Whether any changes were made recently, such as account migration, mailbox changes, license changes, or switching organizations/tenants.

    As To Do data is backed by the Exchange mailbox, this information will help determine whether the issue is related to synchronization, mailbox folders, or potential data loss that may require further investigation by the Microsoft 365 administrator.

    I look forward to your response.
