Hi @S
Thank you for providing the screenshot and the additional information. This is very helpful.
First, let's address your most important concern about losing your new work. You are absolutely right to be worried, and Austin H's warning is correct. Using the "Restore your OneDrive" feature will roll back all files and folders in your OneDrive to a previous point in time. You will lose the new work you have started.
Before we try anything else, please immediately save the new work you've done as a separate file on your computer's local desktop, outside of any OneDrive folder. This will protect it from any recovery attempts.
Now, based on the information you've provided, I have a few questions to help me understand the situation better and provide a more accurate solution:
-To make sure we are looking in the right place, could you please tell me who is the original owner of the document? Are you the owner who shared the file with your friend, or did your friend create the file and then share it with you?
Based on the tags, it looks like you're using macOS. Do you also have a computer that runs on the Windows operating system? Because this is a somewhat complex issue, I need to know more about your environment to troubleshoot it effectively.
Once I have this information, we can work together on the next steps. Warm thanks.
