Excel hyperlinks open pdf files in browser

hi,

We use MS Windows (usually Windows 10), MS Office products and Adobe Acrobat DC.  Our network is based on SharePoint.

When clicking on hyperlinks in Excel (which are linked to pdfs) they default to opening in browser, e.g. Chrome.

Changing Chrome settings to force the pdf to open in Acrobat isn't useful for us as it downloads a copy of the pdf from SharePoint into our local downloads folder.  So any annotations/amendments made to that pdf is the local version.

Does anyone have any tips on how to force Excel to open pdfs in Adobe Acrobat (opening the actual original linked pdf rather than downloading a copy).

Our external IT providers do not have a solution to this problem.

Any help would be appreciated.

Thanks,
