What is the Clutter in Outlook 2016?

Clutter: The E-Mail Server keeps track of the E-Mails that we read and the one that we don’t read. When new mail comes in, the messages that we most likely ignore are stored into the Clutter Folder.

  • We can learn Clutter our preferences.
  • We can see how Clutter filters messages.
  • We can turn Clutter on or off.

What Is Clutter in Outlook 2016

If we have bought Office 2016 and we don’t have an Office 365 subscription, we won’t have access to features such as Clutter.

Clutter can help us first of all to save time for our most important messages. Clutter helps us in order to filter low priority messages. The E-Mail Server keeps track of the E-mail we read and the ones that we don’t. If we turn Clutter on, it is then automated. When new mails come in, the ones that we usually ignore are stored in the Clutter Folder. If we use Clutter often, it gets better and better. If we are not satisfied with Clutter, we can always turn it off.

In order to activate or deactivate Clutter, we must log in to our Office 365 page with our login credentials. Once logged in, at the top left corner we press the App Launcher corner and then from the drop down menu that appears we select the Mail icon as shown in the image below.

Then, from the right corner we select the Settings icon and from the drop down menu that appears and under My App Settings we select the Mail category. Once selected, the Options drop down menu appears where we can see the Mail category activated, where under the category Automatic Processing we select the subcategory Clutter as shown below.

Then, from the middle of the window we notice the category Clutter with the following information:

When E-mail is received:

  • Separate Items Identified As Clutter
  • Send Me Notifications About Message That Are Separated As Clutter

In order to activate the Clutter, we make sure that the check box at the left of the command Separate Items Identified As Clutter is activated, otherwise if we don’t want Clutter to be activated we uncheck the check box. We then press the Save button and we are done.

Clutter Settings

Now, let us see how Clutter works in Outlook 2016. In the top right corner of Outlook 2016 and under Favorites we can see the Clutter Folder. Then in the middle of Outlook where all our new messages arrive we can see all the mail messages that we usually ignore and don’t pay attention to, are stored in the Clutter Folder.


If we want to move a message from our Inbox into the Clutter Folder, we just select the message and then do a right click on it. Then, from the drop down menu that appears we select the command Move To Clutter as shown in the image below. We can also use the drag and drop feature to move a mail into the Clutter Folder.

If we turn off the Clutter feature, the Clutter Folder still remains in Outlook. Once we use Clutter it will take it a few days in order to fully adapt our preferences. The system records our choices and uses the information in order to identify similar messages in the future. This way the Clutter will learn faster our preferences.

If we right click on the Clutter folder the shortcut menu will appear where we can select the command Manage Clutter. Once selected, we will be directed the Outlook Web App in order for us to manage our Clutter options.

Manage Clutter

Before our E-mail messages arrive they are filtered out by Clutter and Junk E-mail. First Junk E-Mail is evaluated and filtered, and then Clutter analyzes the remaining messages and filters out the messages that we ignore or don’t respond to according to our past behavior.

Messages from certain people, ourselves, anyone in our management chain or our daily reports will never be identified as Clutter.

The good thing is that Clutter learns and adapts according to our daily reading habits.
