A Microsoft file hosting and synchronization service.
Hello Michael Surnak.
Welcome to the Microsoft Community.
I'm sorry to learn that you are currently experiencing files being overwritten by an older version in OneDrive, and I fully understand your distress.
Recently in the Microsoft community, many users have reported similar issues, we have collected this feedback and submitted it to the Microsoft development team, they have been informed of the issue and are actively working on a fix, please be patient for a while.
As the OneDrive servers are currently undergoing a data migration, it is true that OneDrive synchronization may be unstable, which can lead to some issues. For your overwritten files, since community members do not have access to the servers to help you recover them, you can contact the OneDrive support team and one of their specialists will get in touch with you and provide you with further assistance.
Thank you for your understanding and support.
Best Regards
Eliac | Microsoft Community Support Specialist
