Overview
Be advised, the default setting in your Outlook E-Mail account as provided by CSULB is to create two inbox tabs -- "Focused" and "Other." Based on your behavior, your most important email messages will show up in the Focused tab, while the rest remain easily accessible, but out of the way, in the Other tab. To remove or add the "Focused" inbox tab, follow the steps below in desired web browser.
Removing Focused Inbox
Removing the "Focused Inbox" in your Outlook E-Mail account will disable the automatic filter that separates your email. This will ensure that no email will become hidden or forgotten in the "Other" inbox tab. Without the filter, every email, including junk, will flow into one main inbox.
This is a feature for various versions of Outlook including: Outlook 2016, Outlook on the web, Outlook.com, Outlook for Mac, and Windows 10 Mail.
See Turn off Focused Inbox for Outlook to view the steps for removing "Focused Inbox" for your specific Outlook version.
Adding Focused Inbox
By default, your campus email account will enable the Focused Inbox tab feature, but if you have disabled it at any point and wish to re-enable it, you can do so as described here. Implementing the "Focused Inbox" will separate your inbox into two tabs, and based on Microsoft's algorithms most of your less important email will go to the "Other Inbox." This allows your inbox to appear cleaner with the emails you likely want to see. The Outlook system is sorting your mail into each tab, and sometimes you can miss important emails that end up in the "Other Inbox." With this, you have to train your inbox by dragging those important emails to the "Focused Inbox."
This is a feature for various versions of Outlook including: Outlook 2016, Outlook on the web, Outlook.com, Outlook for Mac, and Windows 10 Mail.
