Dear Anjan Adhikari1, Good day!Before I give any further advice, could I confirm the following information so that I can narrow this phenomenon:
- Where your files are saved, locally, or in a cloud like OneDrive?
- How did you open the file? Click directly on the file to open it or open it through an Excel application?
- If you open a file in Excel, could you see the path to the file when you open the file?
- If the file is saved in OneDrive, I want to make sure that someone else shared it with you
Knowing the above information can help me narrow down this phenomenon, and I look forward to hearing from you.Sincerely,Tin | Microsoft Community Moderator
