"This workbook contains links to one or more external sources that could be unsafe" when uploading an Excel file
Issue I am uploading Excel spreadsheets to FYI and getting the following message:
"This workbook contains links to one or more external sources that could be unsafe"
Cause This message is a Security Warning that the automatic update of links has been disabled in Excel. A spreadsheet may have a link to another workbook however it can no longer access these and cannot update the links automatically. The existing links are therefore considered unsafe.
To break the links for the specific spreadsheet:
Open the Excel spreadsheet.
Click Edit Links to Files.
In the Edit Links pop-up, if relevant select the link and click Break Link and confirm.
Save the spreadsheet.
Alternatively, to suppress the message so this applies to all Excel spreadsheets and to automatically update the links when you open a workbook, follow these steps:
In Excel, click File.
Under General, click to disable the checkbox Ask to update automatic links.
