Unable to Relink or Remove Missing Links in InDesign

If the IDML route does not fix it as per @Peter Spier and @Abhishek Rao 

Try use File>Package and see if that resolves it 

If that doesn't work there's suggestions in this thread also

There's a simple Applescript as the correct answer from @rob day that seeminly removes broken links

Let us know how you get on.

Hi @Euro30367959x5dj,  

Thanks for reaching out. Could you confirm which version of InDesign you're using and the details of your OS? Also, where are your InDesign file and linked files saved - locally on the system drive, on an external drive, on a remote network, or in the cloud?  

As a test, try creating a new InDesign file and linking the affected file there and let me know if it makes any difference. Also, save your current file as IDML (File > Save As > InDesign Markup Language) and then reopen it to see if that resolves the issue. Let me know how it goes.
