Using Windows 10, 64-bit, with Outlook 2016. I can’t seem to get a PDF Preview in either Outlook 2016 or in Win10 File Explorer’s preview pane. I’ve tried associating PDF files with both Acrobat and with Adobe Reader … that didn’t help. There’s an article here at HTG that describes a fix for this problem, but the latest version of that fix is May 2011, for Windows 7. I’m a little reluctant to try it on Win10.
I’m convinced that there must be an EASY solution to this; if not, zillions of people would be searching online for an answer, and that doesn’t seem to be happening.
