OneDrive and SharePoint automatically save different versions of your files whenever changes are made. This allows you to go back and restore an earlier copy if something is accidentally deleted or changed.
This article explains how long versions are kept and what you can expect when viewing version history.
OneDrive and SharePoint keep file versions for different lengths of time, but older versions are automatically trimmed down over time:
Each document library has a maximum of 500 versions. Once that limit is reached, the oldest versions are automatically deleted to make room for new ones.
Tip: If the version you’re looking for is missing, it may have been automatically removed based on the 500-version limit.
