How can I set Edge-browser as PDF-file previewer in Outlook Desktop?
I wanted the same thing, not needing additional software for the pdf preview in outlook.
Wanting to use edge. However this seems not possible.
I've now found out that when you install Microsoft Power Toys you get a number of cool tools, including a pdf previewer that works in outlook. It is additional software, but at least you don't have to install a separate pdf viewer.
Paul_VC With PowerToys 0.61, MS Office 365, and Adobe DC Pro (but not past the weeklong evaluation period), no preview in Outlook 365.
Edge Beta selected as default application for PDF did not work. Installed PowerToys, also did not work.
I installed the SumatraPDF app (very light, indeed) and the Outlook previewer sprang back to life, AND was able to keep Edge Beta as my default opener for direct viewing of PDF files. I may try SumatraPDF as default, but sticking with Edge as it opens in the existing browser window.
These PDF preview problems have plagued WIndows, Outlook, and Adobe for three decades. As my parents used to say, "we can land a man on the moon [or we could, at one point], but we can't get PDF files to preview reliably."
