Hi QM Chan,
Thank you for giving us the screenshot of the error. It provides more information for our troubleshooting. This error happens when a newer version of the file is on the server, and you don't have any local changes, and you are unable to update the document automatically.
Our suggestion would be the following:
- To change the network, for example if you are using wireless, you can try using internet cable and see if it can resolve the problem.
- Most importantly, other people may have been editing the Excel for web version when you were working on the Excel for the Desktop. Therefore, Open Excel for Web and try to visualize changes they have made on the Excel for Web document located in SharePoint you can’t see on your Excel for desktop. This will allow us to know if there have been changes on Excel for Web that did not sync on your Excel for Desktop.
- Download this specific Excel workbook to your local PC and delete it from SharePoint, after that, upload it again. See if the refresh error will stop prompting in this way.
- As you mentioned, this issue start recently and the workbook was fine before, in that case, if the above method does not work, could you try use the version history function to retrieve this workbook to the time period when it still works.
Note: backup your recent changes in this workbooks first. Otherwise, it might cause data loss issues.
