Dear @Donald Costello,
Thank you for posting your question in the Microsoft Q&A forum. I’m really sorry to hear how much time and effort you’ve spent trying to find your Excel files.
To better assistance, could you please confirm following information:
- Which account were you signed into (university or personal)?
- Were the files saved to OneDrive or your computer?
- Do you remember any file names?
- Have you checked the OneDrive Recycle Bin?
In the meantime, I suggest as below:
- Sign in to OneDrive with your university account and search for .xlsx
- Use Windows search and look for .xlsx
- In Excel, select File > Open > Browse
- Check the Recycle Bin
Also, I want to be transparent that if the files were not saved, were permanently deleted, or were stored under an unavailable account or device, recovery may not be possible.
Please note that our initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution.
I truly appreciate your patience and understanding. If you have any further questions or need further clarification, please feel free to reach out. I'm looking forward to hearing from you.
Thank you for your cooperation.
