I have a simple mailto: link in my PDF. When I click on it in Acrobat Reader, it opens Outlook (like it should). So I know that my settings for Windows are OK (default mail app, how to handle the mailto links, ...)
But when I click on the same mailto link in Acrobat DC, it opens Chrome?!? And yes, in preferences I have indicated that Outlook is my standard e-mail app.
So this seems to be a bug. Is there a way to solve this? Using Acrobat Reader to solve this, is no option.
