Opening PDFs sent to Outlook 365

[Renfield-64]

When any of our Win 10 users receive a PDF via an email in Outlook 365 and they open the PDF it always opens in the browser. Is there a way I can prevent this from happening so that the PDF always opens in Acrobat Reader?

You need to setup default associations.

You can do it through GPO, Adobe give you some templates and examples to do what you want.
