If you’re like most people, you probably find your email inbox cluttered and overwhelming. This is especially true if you use Office 365 for your email. It has a feature called ‘Clutter’ that is designed to help declutter your mailbox by moving lower priority messages into a separate folder. However, if you don’t find Clutter helpful or if it’s causing problems for you, there are ways to disable the ‘Clutter’ feature and regain control over your inbox. In this post, we’ll show you how to do it. Stay organized and productive – follow these simple steps!

Clutter in Office 365

Clutter is a feature in Office 365 that helps you focus on the email messages that are most important to you. Clutter moves unnecessary messages from your Inbox so you can easily scan for the messages that need your attention. Clutter learns from the user’s email habits and gets better over time at figuring out what messages they’re going to ignore. Moreover, you can control whether Clutter is turned on or off for your account, and you can always move a message back to your Inbox if Clutter misclassified it.

If you find that Clutter isn’t moving any emails, or if it’s not moving the types of emails you want it to, there are a few things you can do to improve its performance. First, make sure that Clutter is turned on for your account. You can do this by going to the Clutter page in Office 365 settings. Next, take a look at your email habits and see if there are any patterns that Clutter isn’t picking upon. For example, if you always delete messages from certain senders without reading them, Clutter might not realize that these messages are a low priority for you.

But as some users rely on rules for managing the mails, this Clutter feature is unnecessary for them. Also, users who complain about not finding the emails crucial for them in their Inbox can check for the emails in Clutter. So, they can consider disabling this feature.

Here we are discussing two ways for disabling the Clutter feature, one for administrators and the other for end users.

How Can Office 365 Administrators Disable Clutter?

Though a useful feature, Clutter can be a nuisance sometimes. So, Office administrators can disable this feature for users. Here is how they can do this:

Open Windows PowerShell on your system. Connect to Office 365 using these steps:

  1. Run this command first.
    $UserCredential = Get-Credential
  2. It will ask for the Office 365 login credentials. Enter your Office 365 username, and password then click OK.
  3. Now, run these two commands one after another.
    $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri -Credential $UserCredential -Authentication Basic -AllowRedirection

    Import-PSSession $Session -DisableNameChecking

  4. Office 365 account is successfully connected through PowerShell. Execute this command to disable the Clutter feature for Office 365 mailboxes.
    For Single Mailbox –

    Set-Clutter -Identity “user name” -Enable $false

    For Multiple Mailboxes –

    $users = “user name 1″,”user name 2”
    ForEach ($user in $users) {
    Set-Clutter -Identity $user -Enable $false

    For All Office 365 User Mailboxes

    Get-Mailbox -ResultSize Unlimited | Set-Clutter -Enable $false

    Note: You can enable the clutter feature for your Office 365 mailboxes, by just passing the true value to -Enable parameter as shown:

    Set-Clutter -Identity “user name” -Enable $true
How Can Office 365 End Users Disable Clutter?

Office 365 end users can also easily disable/enable the clutter feature in their mailboxes. Open your mailbox and follow these steps:

  1. Go to the gear-shaped Settings icon and search for the ‘clutter’ word. Click on the Clutter option.
    Click on the Clutter option
  2. Now, clear the checkbox “Separate items identified as clutter” and click on Save to save the settings.
    save the settings

This will disable the clutter feature in your Office 365 mailbox.

Note: As per Microsoft sources, Clutter will be replaced with a new feature, namely, Focused Inbox.


If you are an Office 365 user, you may have noticed the ‘Clutter’ folder in your mailbox.
