If your organization's email service supports it, you can use the Focused Inbox. This tries to separate important emails from less-important ones.
Click the View tab.
Click the Show Focused Inbox button.
The inbox is sorted into two groups, Focused and Other. Outlook will sort emails from people you email frequently into the Focused inbox, while sorting emails from other people, and automatically-generated email notifications, into the Other inbox. It will also learn your habits over time.
