This is when trying to open certain PDFs from Windows Explorer from Teams file shares.  The status icon is the green check mark which should indicate the file exists on local storage.

When opened directly from Teams we don't get this message.

What does this tell us, and is there a log file that has further info about the error?

Is that only with PDF files?

That does not mean that you have the right to open that file. What happens, when you open the PDF file with Notepad (or Notepad++). Obviously, it won't display the PDF file correctly as a PDF file, but it will confirm that the user can open the file.
