***Important changes that may impact Guest User Visibility in Salesforce Communities**

Community Cloud Trailblazers - As you may know, Guest User Visibility is a Community level preference that grants the guest user access to see logged in members of the community.  It was introduced In the Winter ‘20 release and is controlled through the Let guest user see other members of this community setting.

We want to make you aware that in the Winter ’21 release, we will default OFF the community-specific Let guest users see other members of this community setting for all communities in orgs where at least one community was created prior to the Winter ‘20 release (October, 2019). Continue reading to understand the impacts and how you can opt-out if the setting is required for your community.

About the Setting: When ON, this setting may allow a guest user to access community users’ (authenticated users) personal information like first and last name, email, and other fields.

Impact of turning setting OFF:  Guest users will not be able to see logged in members of the community.

Below functionality will be impacted:

• Chatter feeds will not show
• Leaderboards and other people lists will not show
• User search will not return results
• Custom APEX implementations that query for users will not return results

Keeping the setting ON (Opt-Out):  If one or more of your communities require the Let guest users see other members of this community setting to be ON, you can opt-out prior to Winter ‘21 release via the Opt Out of Turning Off Community-Specific Setting for Guest Users to See Other Members (https://releasenotes.docs.salesforce.com/en-us/summer20/release-notes/rn_networks_GUV_opt_out.htm) critical update located in Setup > Critical Updates.  Activating the update ensures that communities will not be affected by this change.
