Outlook Changes

Focused Inbox

By default, Office 365 Outlook will have a “Focused” inbox enabled. The Focused Inbox 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. This can be an inconvenience if you are accustomed to having all your email appear in one place until you decide to move them. You can disable this option by following these steps:

1. Open Outlook
2. From the Outlook menu, select Organize

Outlook for Mac Organize tab selected

3. Notice the shaded square around Focused Inbox. Click on it to disable Focused Inbox.
