Excel Data Missing

Hello,

I have an Excel workbook stored in my personal OneDrive that I have been editing through Excel Online.

My workbook contained several months of data, including changes made as recently as November 4, 2026. About a week ago, the newer data was still present.

The workbook now appears to have reverted to an older version. The latest version available in OneDrive Version History is April 8, 2026, and the file is currently 46 KB.

I have checked the OneDrive Recycle Bin, Version History, and Restore Your OneDrive, but I cannot recover the missing data.

The workbook was accessed using the same personal Microsoft account on two laptops.

Can you investigate whether any additional recovery options, retained versions, or cloud-side backups are available for this workbook?

Thank you.

    If the November workbook is absent from OneDrive’s web Version History, Recycle Bin, and the available 30-day OneDrive restore points, there is no additional user-accessible cloud version or backup to restore; the remaining recovery opportunity is to locate a separate or locally cached copy on either laptop.

    OneDrive retains file version history for 30 days, and Restore your OneDrive can undo file actions only within the previous 30 days.^1^^2^ Because those cloud recovery methods have already been checked, do not run Restore again unless its activity feed showed a relevant overwrite event that was not selected previously.

    Check both laptops without allowing another overwrite

    1. Pause OneDrive synchronization or disconnect each laptop from the network before opening suspected copies.
    2. On each laptop, search File Explorer for:
      • The workbook’s exact name and partial name.
      • *.xlsx, *.xlsm, and *.xls.
      • Files modified around November 4, 2026.
      • Names such as Workbook (1).xlsx, Workbook - Copy.xlsx, or similarly named files in Downloads, Documents, Desktop, and the local OneDrive folder.
    3. Sort the results by Date modified and Size. A larger or recently modified copy may contain the missing months.
    4. Copy each candidate to a folder outside OneDrive and rename it before opening it. This preserves the candidate and prevents synchronization from replacing the cloud file.
    5. Check the Windows Recycle Bin on both computers.
    6. For a candidate local file or its containing folder, select Properties → Previous Versions. This works only if Windows File History or another backup had already been enabled.^3^

    Microsoft’s missing-file guidance specifically recommends searching local device storage when a file may not have synchronized to OneDrive.^4^

    Conditional Excel recovery checks

    These apply only if the workbook was ever opened in the desktop Excel application on either laptop; edits made exclusively in Excel for the web normally would not create a desktop AutoRecover copy.

    On each applicable laptop:

    1. Open Excel without opening the OneDrive workbook.
    2. Select File → Info → Manage Workbook → Recover Unsaved Workbooks.
    3. Also check File → Open → Recover Unsaved Workbooks, if shown.
    4. Open any plausible recovery file and immediately use Save As to save it outside OneDrive under a new name.
    5. In desktop Excel, open the current workbook and check File → Info → Version History. This ordinarily reflects cloud history, but it is a final interface-level check for a version not noticed in the OneDrive pane.^5^

    If Review → Show Changes is available, it may identify saved cell changes, but it is not a backup and may be empty after a file was uploaded, copied, or replaced.^6^

    Check for another file object

    Even when both laptops used the same account, search OneDrive on the web using partial names, xlsx, and distinctive terms. Look in all folders and Personal Vault, not only the workbook’s expected folder. A save-as, upload, or replacement can create a different file object whose history is separate from the current 46 KB file.^4^

    Also inspect browser download folders on both laptops in case the workbook was downloaded or exported before the reversion.

    Cloud backup and support limits

    OneDrive’s datacenter replication protects service availability; it is not an additional customer-visible archive from which an individual personal file can be selected. The documented personal recovery mechanisms are Version History, Recycle Bin, and—when subscribed to Microsoft 365—Restore your OneDrive.^7^

    Microsoft Support can be contacted to report the unexpected reversion, supplying the filename, approximate last-known-good time, current size, and the two devices involved. However, support agents are not permitted to access personal account files and cannot recover a missing version beyond the documented personal recovery options.^4^

    If none of the two laptops, local backup/Previous Versions, AutoRecover locations, duplicate-file searches, or browser downloads contains the newer workbook, the November data is not recoverable through the documented personal OneDrive mechanisms.
