A Microsoft file hosting and synchronization service.
Recover each affected file through OneDrive Version History first, selecting the version dated November 11, 2026 and opening it to verify the contents before restoring it.
1. Preserve any newer local copies
Before changing cloud versions, check the Windows PC and any other device used on November 11:
- Open File Explorer and search by the file name.
- Check the local OneDrive, Documents, Desktop, and Recycle Bin folders.
- If a copy contains the November edits, copy it to a folder outside OneDrive or to external storage before opening or saving the cloud copy.
This prevents a potentially unsynced local copy from being replaced while recovery is underway. Microsoft also recommends checking local device storage when files have not yet synchronized to OneDrive.^1^
2. Restore the November 11 version
Use the OneDrive website rather than relying only on the synced folder:
- Sign in to OneDrive with the account that owned the affected files.
- Locate an affected file.
- Right-click it and select Version history.
- Find a version timestamped November 11.
- Open or preview that version and confirm it contains the latest work.
- Select … beside that version, then Restore.
The selected version becomes current, while the version it replaces remains in the history. Version History supports all file types and retains versions for 30 days; for a work or school account, an administrator may have disabled versioning.^2^
For Word, Excel, or PowerPoint, another route is:
- Open the file.
- Select File > Info > Version History.
- Open the November 11 version in a separate window.
- After verifying it, select Restore.^3^
Repeat this one file at a time.
3. If many files reverted at once
If numerous files are affected and the correct individual versions exist, restoring them separately is safer. If that is impractical, Microsoft 365 subscribers can roll their entire OneDrive back to a point within the last 30 days:
- On the OneDrive website, select Settings.
- For a personal account, select Options > Restore your OneDrive.
For a work or school account, select Restore OneDrive. - Select Custom date and time.
- Use the activity chart and feed to locate the event that caused the files to revert.
- Select the earliest activity to undo, review all selected subsequent activities, and select Restore.^4^
Caution: This rolls back all selected OneDrive activity, not just the affected documents. Files created after the chosen restore point are moved to the OneDrive Recycle Bin, where they can be restored. Preserve important current files before proceeding.
4. If November versions are absent
Check these locations without overwriting the September copies:
- OneDrive Recycle bin: On the OneDrive website, select Recycle bin, choose the relevant files, and select Restore. Personal-account deletions are normally recoverable for 30 days; work or school deletions for 93 days unless the administrator changed retention.^5^
- Another Microsoft account: Confirm that the November work was not saved under a different personal or work/school OneDrive account.
- Other devices: Search any PC or device used to edit the files, particularly if it may not have completed synchronization.
- Work or school account: Contact the organization’s IT administrator with the file names, approximate last-known-good time, and editing device. The administrator can investigate retention and tenant service health.
- Personal account: Use Contact Microsoft Support from the OneDrive recovery page. Support cannot inspect file contents, so provide file names and timestamps but no sensitive content.^4^
If neither Version History, the Recycle Bin, an entire-OneDrive restore point, nor an unsynced device contains the November data, the available recovery records may not include that version.
