How do I restrict User Access to a post?

1. In your inbox, click the Edit post icon (pen) and then click User Access at the top of the Edit post form.
2. Change from Normal to Restricted.
3. Search and add users and user groups who will have access to the post.

The default access level is Normal which means that all users have access to the post.

User Access: The Inbox module is only available for Wide Narrow Superusers.
