With online version history, you can see and restore older versions of all your files in your OneDrive. Version history works with all file types, including PDFs, CAD files, photos, and videos. If you need to, you might be able to Restore Deleted OneDrive Files.
1. Sign in to OneDrive using your TechID and password.
2. Right-click the document for which you want to restore an earlier version, and then click Version history.
3. Version history appears in the Details Pane. Select the ellipses (...) next to the version of the document that you want to restore, and then click Restore.
4. If you see a confirmation message, click OK.
The document version you selected becomes the current version. The previous current version becomes the previous version in the list.
