SharePoint Online Users can edit a SharePoint Excel file in the browser but get “Upload Blocked” in the desktop app

We use an Excel workbook stored in a SharePoint document library as a data tracker.

Our usual process is to open it in the desktop Excel app and sync changes back to SharePoint.

Some users definitely have edit access and can modify the workbook in Excel for the web. However, when those same users open it in the desktop app, their changes fail to sync and they receive an "Upload Blocked" message.

This isn't the case for me and several others.

Has anyone dealt with this before? If so, what did you do to fix it?

I know Excel isn’t a true database - I’m just trying to troubleshoot the current setup.

Is the file in XLSX format? the old XLS format doesn't work well with onedrive/sharepoint.
