Check out/in pdf in SharePoint 2013 not working
In our SharePoint 2013 environment, we have a library of documents that contains pdf's, excel's, and word docs. Our excel's and word docs work fine but when it comes to pdf's they do not.
The way that it should work, and it works for microsoft docs, is that when you click a pdf document it should:
1. Launch Adobe Acrobat
2. Prompt Check-Out of document
3. Allow the user to edit the pdf
4. The user closese the document
5. A prompt to Check-In is given
5. The document is updated with the newly edited version in SharePoint.
Unfortunately this is not how it's working. At the moment when you click a pdf it just opens within the browser with no check-out/in prompts and you can't edit. This issue is only occuring in Chrome and Edge. It does work in internet explorer but our users do not want to have to use IE. We do have a work around at the moment that they can copy the url to the file and open it through acrobat with the direct url but that's just a temporary solution.
Any help would be appreciated. Thanks!
