Try to start Adobe specifically with the link and pass the file name as an argument.
C: \ Program Files (x86) \ Adobe \ Acrobat Reader DC \ Reader \ AcroRd32.exe "filename.pdf"
(The prerequisite for this to work is that you have Adobe Reader DC on your laptop at the address given, and the name of the pdf file is spelled correctly. If it is not, you would have to adapt the argument to your needs)
If it doesn't work, the PDF should appear read-only.
Your administrator has to give permission.
If the file opens then the link is probably broken.
However, I can only guess that you didn't insert a file (without sensitive data) to be safe.
I don't even know which Excel version and operating system you have on your laptop.
So you make the helpers life harder than it could be:)).
I would be happy to know if I could help.
