OneDrive replaces newer versions of files with old versions

So, has anyone already foud a solution to this issue?

I have been working on several Excel files for weeks now.

I know these files have been synced to Onedrive as I and some of my employees have been able to open the files and edit them as well.

I just restarted my PC as it needed an update, and upon opening just now I wanted to continue working on those files, but these files have been replaced with versions from dec. 12th and dec. 21st.

From both files, the version info states these files are the newest versions of the files, however I am sure there have been newer versions which were synced. I have tried resetting Onedrive in the Onedrive webpage to a version from yesterday, but this did not do a thing. It does not show replacing the file in the history tracker either.

How is it even possible Onedrive just replaces these files with old versions, and how do I get my data back?

Hey, you don't understand the issue. The newer files are overwritten by the old ones without ever opening them! Just by booting a laptop I got all newer versions overwritten (many files) without opening any of them. This is the problem many people here are describing.

I had the same issue: booted laptop that was turned off for several months and OneDrive overwritten all newer versions of files with the versions from the laptop. Thanks Joel for your advice - I was able to save a lot of work by going online and downloading newer versions from the history. As mentioned by previous people, using history from Explorer did not work.

I had same issue with an earlier version writing over latest version as described, but was able to successfully restore a newer version from web interface. I have Office 365

Here is what happened :

* updating an Excel file each day on desktop, windows 10

* powered up laptop that is synced with Onedrive. Did not open any files on laptop.

* found that version on desktop had been overwritten with weeks old version of Excel file

* tried to restore previous version from Windows explorer using version history. Would not restore. Looked at version using Windows explorer and all the versions there pointed to weeks old version (even ones dated prior to that version)

* went to online version of Onedrive using Chrome, selected file I needed (its a check box) and in version history option was able to download a previous version that was just one day old. So that version contained the correct and current data.

** renamed downloaded version to a new name, just to be sure it did not get overwritten again.

This overwriting problem needs to be fixed!

Good luck!

I gather that opening an old version on another device before OneDrive syncing is up-to-date is one of the problems. OneDrive file updating stops when the file is open. So, if you start working on the old version before it is current, then OneDrive is confused and saves that old version, thinking that it is the latest version.

Definitely, the editor must close to sync. After you close the editor, do you see the changes uploading at the cloud icon on the taskbar? Don't shut down your computer until OneDrive is up to date.

I don't work for Microsoft. I suggest you type "feedback hub" into the Start menu and send feedback to Microsoft. Also, Email the OneDrive support team directly and let them know.
