Use Clutter to sort low priority messages

Clutter moves your low priority messages out of your Inbox so you can easily scan for important messages. Clutter analyzes your email habits, and based on your past behavior, it determines the messages that you’re most likely to ignore. It then moves those messages to a folder called Clutter, where you can review them later.

Note: We strongly recommend that you do not treat Clutter as an 'ignore' pile of messages.  The process for identifying messages may mark important messages as Clutter.  You should check your clutter folder on a regular basis!

Turn Clutter on

  1. Sign in to Outlook on the web. 

  2. Go to Settings Settings: update your profile, install software and connect it to the cloud > Options.

    Outlook on the web Settings Options

  3. On the left nav bar, go to Mail > Automatic processing > Clutter.

  4. Select Separate items identified as Clutter, and then click SaveSave.

Help Clutter learn your preferences faster

It might take Clutter a while to fully adapt to your preferences as it records your choices and uses that information to identify similar messages in the future. But you can help Clutter learn your choices faster by doing the following:

  • If you see a message that was sent to Clutter by mistake, move it from the Clutter folder to your Inbox.

  • If you see a low priority email in your Inbox, move it to the Clutter folder.


How Clutter filters messages

Clutter and junk email are both filtered before they reach your Inbox. Messages identified as possible junk email are automatically moved to the Junk Email folder, and any potentially dangerous content, for example links or attached programs, are disabled.

Then Outlook processes the rules, if you have set up any. 

If you've used Sweep, messages will be managed based on the settings you chose. 

Next, Clutter analyzes the remaining messages and filters the types of messages that you usually ignore or don't respond to, based on your past behavior.

Messages from certain people will never be identified as clutter:

  • You

  • Anyone in your management chain, if you're anOffice 365 Business user.

  • Your direct reports, if you're an Office 365 Business user.

Clutter looks at various aspects of messages to understand what you don’t typically read, for example:

  • The sender

  • Whether you’ve participated in the conversation

  • Whether you’re the only recipient

  • The importance

As your reading habits change, Clutter learns and adapts.
