Regards, Steve Fan TechNet Community Support. If this issue continues when previewing a PDF attachment in Outlook, I'd recommend we uninstall and then reinstall the Adobe reader to see the result. If it's not a PDF document that you want to preview, we can also try to preview a PDF attachment to see if it works fine. Having issues with your PDF previews working with Microsoft Outlook or Windows Explorer on a 64-bit version of Windows? Turns out the problem is that Adobe sucks, but a quick registry hack can save the day.įor example, when I try to preview a PDF in Outlook, I get the message “This file cannot be previewed because of an error with the following previewer: PDF Preview Handler for Vista”.
