Immutability and retention are an issue with all digital information outside a properly configured and standards-compliant electronic records system - and even then there are limitations.
OneNote can get close enough for most purposes however - it can be configured to auto-backup to any location at configurable time intervals. Use file-history, time-machine, rsync, etc. from there. Zip, digital-sign and timestamp the backups and store in your records management system or file directly with multiple sets of lawyers around the world. Once your backups grow to significant size, realise you needed a retention and disposal policy and mechanism...
Also, be aware that nothing is perfect - permanency of paper stores is often overestimated. Anything that is ever referred to (and if not, why are you keeping it?) needs a checkout/checkin/refile process all of which involves risk of loss. Temperature, humidity, mold, vermin, can all bite you badly, before you even get to the more obvious ones of the single cigarette-end or burst water pipe.
