Always open PDF files externally

Disables the internal PDF viewer in Microsoft Edge.

If you enable this policy Microsoft Edge treats PDF files as downloads and lets users open them with the default application.

If you don't configure this policy or disable it, Microsoft Edge will open PDF files (unless the user disables it).

Supported on: Microsoft Edge version 77, Windows 7 or later
