What is the best way to ensure all external users can see each other regardless of their accounts?

Selecting Site User Visibility and enabling member preferences is the best approach to ensure all external users can see each other, regardless of their accounts. This setting allows you to control how users can interact within your Experience Cloud site. By enabling member preferences, you ensure that users' visibility settings allow them to view and engage with one another, fostering collaboration and interaction among external users.

When Site User Visibility is enabled, it opens up the necessary permissions that facilitate visibility, which is crucial for external users who may be collaborating on projects or sharing information. This not only enhances the community feel but also allows users to leverage the network effectively.

The other choices do not promote the desired outcome of ensuring external user visibility. Deselecting Site User Visibility would limit user interactions, while enabling Guest User sharing primarily concerns non-registered users, and restricting access to certain records could isolate users from each other, cutting down on collaborative opportunities. Thus, enabling Site User Visibility paired with member preferences is the optimal choice for enhancing connectivity among all external users.
