Clutter

What is Clutter?

The Clutter feature of Office 365 and Outlook 2016, which is switched on by default for all accounts, reacts to the email reading and deletion behaviour of users in an attempt to determine whether future emails of the same kind should be handled in the same way they regularly have been, moving any that are generally ignored or deleted without being read into a separate 'Clutter' folder.

How Clutter works

Clutter and junk email are both filtered out before they reach your Inbox. Junk email is evaluated and filtered first, then Office 365 processes any email rules (if you have set up any). Next, Clutter analyzes the remaining messages and filters out the types of messages that you usually ignore or don't respond to, based on your past behavior, and moves them into the 'Clutter' folder in your list of email folders.

It 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.
• If you’re the only recipient.
• The importance.

As your reading habits change, Clutter learns and adapts.

Clutter FAQs

Why has a particular email been moved to my Clutter folder? - Clutter only responds to your past email behaviour. If you previously always deleted unread messages from this sender, or routinely ignored them and left them unread, Clutter will consider them ones that should be filtered out.
