I have an excel file being shared on Microsoft Teams so multiple users can access it. Users have been complaining that they get a message "Unable to Refresh". After reviewing, it appears the excel file is linked to another remote file. It doesn't need to be linked to any other files, as all formulas are in my workbook. In both Microsoft Teams and in the excel file on my desktop, I've tried to break the link, but nothing changes when I follow steps to break the link. How do I permanently break these links?
