SharePoint on premise anonymous open documents in browser instead of client application

Question

Hello,

I have an external SharePoint site where Anonymous access is enabled for the entire site. I've activated the “Open Documents in Client Applications by Default” feature. Also, on the site document library, advanced settings, under “Opening Documents in the Browser”, I've selected “Open in the client application”.

As an anonymous user, when I open an office document, it opens the file in the browser. When I open a PDF, it prompts me to login. As an authenticated user, when I open an office document, I get a prompt to open the file in the client application. When I open a PDF, the file displays in the PDF reader.

How can I force all files to open in the native application when accessing the site as an anonymous user?

Hi @MDuBose ,

As I couldn't reproduce this issue on my end and this issue only occurs in part of your site collections, it doesn't seem to be a bug. Maybe there is something wrong in your backend. You can check ULS logs and see if there is any related error messages. Also, you can open a ticket with Microsoft. Experts there will give you instant help.
