In this post I describe how to disable/enable the Clutter function of O365. The clutter feature is self learning and there are not many options you can specify. You can drag messages to and from the Clutter mailbox so that it can learn how to work. But sometimes you want do disable this function for specific mailboxes.
To disable Clutter for the entire organization you can use the following Powershell command:
Get-Mailbox | Set-Clutter -Enable $false
To disable Clutter for a single mailbox use the following command :
Set-Clutter -Identity helpdesk -Enable $false
To enable Clutter replace $false by $true
