Enabling the Focused Inbox (Clutter) feature in Outlook on the web


Focused Inbox (formerly known as "Clutter"), is an email filtering option available to Microsoft 365 users.  It is similar to an anti-spam filter as it moves less important emails (based on your reading habits) into an 'Other' folder where they can be ignored or reviewed later.  Most of the mail going into the folder should be bulk mail (advertisements) and messages from mailing lists.  However, you will want to periodically check the 'Other' folder as it may move legitimate emails into this folder.
