The Exempted List is a list that stores the users, groups, or domains that are exempted from IM Security enabled rules matching. Use this list to define the persons or groups in your organization that IM Security exempts from File Blocking, Content Filtering, and Data Loss Prevention. Similar to the Selected List, the Exempted List is not a global list—it varies per rule. Add users, groups, or domains in an Exempted Contacts list when creating a rule.
