Strange http link message in Workbook with macros

[LydiasDad]

I have a workbook with macros. When I open the workbook, without even running any macros, I get a message indicating that it's looking for an old workbook on an intranet that no longer exists. I'm not referencing the link in any of my macros, and I'm not aware of any macro running upon workbook open. I've checked all document properties and I can't find any reference to the link.

Any idea where this link might be? Picture attached.

Anyhow try this, press Alt+E+K and check whether is there any external references, if so then Click Break Link

Nothing attached.
possibly try and find "[" in formulas, using the find function

Is "Alt & E & K" the same as "Ctrl & H" ?

Yes, exactly same key combination
