Dear Sylvie,
Good day! Thank you for posting in Microsoft Community. We are happy to help you.
Per your description, I understand that you are experiencing issue with SharePoint files, when you open the file in Excel desktop application, it shows old version, not the latest version.
I'd like to help you, we can work together to narrow down the situation and work towards a resolution path.
I notice you mentioned that you can access this file from a browser to share point, it showed up the latest version and you can also edit it.
You may try steps below:
- Close the Excel file. Sign out your account from Excel desktop app, quit Excel app.
Open Excel app again, sign in with your account which has permission to access the SharePoint file.
2.Go to SharePoint in browser, find your Excel file, open it in Excel Online firstly.
From upper-right corner, click Editing > Open in Desktop, as shown below. Open it in Excel desktop app again. Try editing it and check the result.
- You may try clearing cache files from Excel desktop app > File>Options > Save > Cache Settings > Delete cache files > click OK.
If the Excel file still shows old version when you open it in Excel desktop app, I understand how frustrating this situation can be and sincerely apologize for the inconvenience caused.
Let me help you further. I would appreciate if you could share following information:
1.Does this issue happen when you open a specific Excel file or different files?
2.May I know if other users who have permission to access the same Excel file also experience this issue? I'd like to check if this issue only occurs in your Excel desktop App.
3.What is the version of your Excel desktop App? Please go to File > Account, capture a full screenshot of Product Information and share it here.
Look forward to your reply. Thanks for your time and cooperation!
Please understand that our initial reply may not always immediately resolve the issue. However, with your help and more detailed information, we can work together to find a solution.
Best Regards,
Tina
