The behavior you're experiencing with PDF files is likely due to the default security settings in Adobe Acrobat or Reader. By default, Adobe products will not allow PDF files to be opened from untrusted locations, such as an anonymous SharePoint site.
To force PDF files to open in the native application when accessing the site as an anonymous user, you can try the following steps:
Open Adobe Acrobat or Reader.
Go to Edit > Preferences > Security (Enhanced) > Privileged Locations.
Click on "Add Folder" and select the folder where your SharePoint site is located.
Click on "OK" to save the changes.
This should add the SharePoint site to the list of trusted locations in Adobe Acrobat or Reader and allow PDF files to be opened in the native application.
Additionally, you can also try adding the SharePoint site to the list of trusted sites in your browser's security settings. This may help to prevent any browser-based security warnings or prompts that could interfere with the file opening in the native application.
Note that forcing files to open in the native application for anonymous users can be a security risk, as it may allow malicious files to be downloaded and executed on a user's computer. Therefore, it's important to ensure that your SharePoint site is properly secured and that you trust the files being downloaded from the site before implementing this solution.

Thank you for this information. In order for these steps to work, the user accessing the site would have to perform these steps in their Adobe and/or browser, correct? As the Site Collection Admin, is there a global setting that could work in this case? Also, opening a office document like word or excel, in it's native application doesn't work for anonymous users. Is their a way to make this behavior work for anonymous access?
- jhallalMar 29, 2023Copper ContributorIt is correct, I meant that the user should perform these steps in their Adobe and/or browser.
- mduboseMar 29, 2023Copper ContributorIs there any way to fix the issue with office documents? In other words, office documents are not opening in the client applications when anonymous user access them. These documents open in the browser. However, this is not the case for authenticated users.
