Manage Which Custom Object Records Can Be Added to Groups

Starting with Summer ’15, you can choose which custom object records users can add to groups. Previously, all custom object records were allowed. This feature gives you more control over the type and number of custom object records that users can add to groups going forward.
For each custom object you want to manage, select the Allow in Chatter Groups option on the custom object detail page, under Optional Features.
Note

Note

Custom object records added to a group prior to Summer ’15 won’t be removed and will continue to appear in the Group Records list. Be sure to enable this feature for each existing custom object that you want to allow in groups.
