Focused Inbox helps you focus on the emails that matter most to you. It separates your inbox into two tabs—Focused and Other. Your most important emails are on the Focused tab while the rest remain easily accessible—but out of the way—on the Other tab. You’ll be informed about email flowing to Other, and you can switch between tabs at any time to take a quick look. 

Focused Inbox is on by default for many but not all new Office 365 accounts. Click on the link below to learn about how Focused Inbox works and how to turn it on or off as desired. This article is relevant to Outlook on the Web and Outlook 2016.
