Clutter is designed to help you focus on the most important messages in your inbox. It uses machine learning to de-clutter your inbox by moving lower priority messages out of your way and into a new Clutter folder.
The Mailbox Clutter Settings report shows you which users have Clutter enabled.
You can use the filters under the graph on the left hand side of the report to return users that have Clutter Enabled, Disabled or all Users and their settings.
The standard Cogmotive Filters can also be used to return the Clutter settings for a particular Department or any other group of users.
