Our admin staff frequently use Adobe Acrobat Pro to manipulate and combine multiple MS Word files into one PDF. Doing this natively from within the Adobe product (by pasting a link to the SP library in the file browser dialog) opens the MS Word file as a temp ‘pdf’ which can then be manipulated as required or they can be individually opened from the ‘combine files’ dialog box. It is easy to then save the pdf to their SharePoint library using OnePlaceDocs (great) but they would also like to easily open the MS Word files without having to find the URL and paste each time. They’ve tried this and found the following limitations when using OnePlaceDocs:

Double clicking a single MS Word Doc to open via OnePlaceDocs within Adobe opens the file in MS Word.
Highlighting a single MS Word Doc, selecting ‘Open With’ and choosing an Adobe Acrobat results in an error message.
Selecting multiple MS Word files greys out the Open With option.

We're using client version 7.7.0 with SP2013 on prem.

Is there something I can change in the configuration tool to make the MS Word files open with Adobe products?

Many thanks in advance
