Use Microsoft Clutter to sort low priority messages in Outlook Web App
Clutter and junk email are both filtered out before they reach your Inbox. Junk email is evaluated first, and filtered based on the characteristics of the messages themselves, for example the subject or the server it was sent from. Next, Clutter analyzes the remaining messages destined for your Inbox, and filters out the types of messages that you usually ignore or don’t respond to, based on your past behavior.

Help Clutter learn your preferences faster
It might take Clutter a few days to fully adapt to your preference, as the system records your choices and uses the information to identify similar messages in the future. But you can help Clutter learn your choices faster:
- If you see a message that was sent to Clutter by mistake, right-click the message and choose Move to inbox.
- If you see a low priority email in your Inbox, right-click the message and choose Move to Clutter.
Note Moving an email in or out of the Clutter folder, from any of your devices, is enough to give the signal to the Clutter system that an item is Clutter or not. For example, if you move an email to the Clutter folder in Outlook desktop, or the Mail app on your phone, the action gets recorded in the Clutter system on all your mail apps. You don’t have to do this individually in each app.
How Clutter filters messages
Clutter helps you focus on what’s important by automatically filtering out messages you’re not likely to read. Messages from certain people will never be identified as clutter:
- Anyone in your management chain
- Your direct reports
For mail from everyone else, you teach the system what kinds of content interest you by interacting with your mail. No extra work is required. Clutter learns which kinds of messages you frequently read and uses that to determine if a new item is likely clutter or not.
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
- If you’re the only recipient
- The importance
As your reading habits change, the Clutter feature learns and adapts.
