This article is just a guide for Office 365 Administrators and explains how you can enable or disable Clutter for a particular user or all users.

Firstly, connect to Office 365 using PowerShell.

Step 1 - Connect to Office 365 through Powershell

Firstly, you need to create a connection to Office 365. You can do this by typing (or copying/pasting) the following into Powershell:

$session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri "https://outlook.office365.com/powershell-liveid/" -Credential $cred -Authentication Basic -AllowRedirection

Once this is in the Powershell window, press Enter to execute the command.

Now you simply type in the username and password for an Administrator account in your Office 365 tenant and click OK.

You will probably see some warnings. Don’t worry, they are normal.

You are now authenticated into Office 365. The last step is to connect up to Office 365 by using the following Powershell command:

Import-PSSession $session

Congratulations! You’re connected!

Step 2 - Enable or Disable Clutter feature

To enable Clutter for one user:

PS C:\Scripts> Set-Clutter -Identity [email protected] -Enable $true

To disable Clutter for one user run:

PS C:\Scripts> Set-Clutter -Identity [email protected] -Enable $false

To enable Clutter for all users:

PS C:\Scripts> Get-Mailbox | Set-Clutter -Enable $true

To disable Clutter for all users run:

PS C:\Scripts> Get-Mailbox | Set-Clutter -Enable $false

During the execution of the Set-Clutter cmdlet you will see the following code printed on prompt repeatedly (the whole process could take a long time on a Office 365 tenant with many mailboxes and users: this behaviour is correct if the value of IsEnabled is False and IsValid is True).

RunspaceId  : XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX
IsEnabled: False
Identity:
IsValid: True
ObjectState: New
