A family of Microsoft word processing software products for creating web, email, and print documents.
Dear YA,
Thanks for your updates with further information.
Sorry for that I don't consider the shared files in a shared folder in OneDrive for Business.
Yes, I can reproduce the issue with the shared files in OneDrive for Business. The update object type will be automatically changed to the whole worksheet when you change the source of the file.
As a workaround, you may only create a new link from another file and then break the previous link and then manually remove the cell value in Word.
As our product developers are willing to hear users' requirements, I suggest you submit your feedback and convey your suggestions to our new Feedback platform mentioned in the following article for the product developers to know your suggestions and opinions for product improvements.
