Clutter in Outlook


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

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, 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.

Clutter and junk email are both filtered out before they reach your Inbox. Junk email is evaluated and filtered first, then Outlook processes the 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.

Messages from certain people will never be identified as clutter: You, anyone in your management chain and your direct reports. 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 and the importance. As your reading habits change, Clutter learns and adapts.

You can turn Clutter off at any time in Outlook Web App. Sign in to Outlook Web App. Then go to Settings>Options>Mail>Automatic processing>Clutter. Select Don't separate items identified as Clutter, and then click Save. NOTE: The Clutter folder remains in Outlook after you turn off Clutter. If you don’t want the folder listed under your Mailbox, move the emails from Clutter to other folders as appropriate, and then delete the Clutter folder.
