Using New Outlook on Windows for personal email, calendar, and contact management
HiMichael SB66,
Greetings!
Thank you for posting in Microsoft Community.
Based on the description you posted, it seems that you have an issue with MS Office wherein you want to know how to re-add your daily calendar view on the New Outlook as it suddenly disappeared.
Let’s work together in finding the best solution to this issue.
For me to better understand the issue, I’d like to ask a few questions:
• What is the current build number of your Outlook program?
• What is the current MS Office license you are using? (M365 for home and personal or M365 for business)
• What other troubleshooting steps have your tried so far? Aside from the one's you have already mentioned?
In the meantime, we would like you to try the steps provided down below:
Keep upcoming appointments and meetings always in view
Outlook for Microsoft 365 Outlook 2021 Outlook 2019 Outlook 2016 Outlook 2013
When you point to the Calendar icon on the navigation bar, the Calendar peek shows your upcoming appointments and meetings. To always be able to see your upcoming items, dock the Calendar peek to the Outlook window.
- Click
(highlighted in red in the picture below) or right-click the calendar icon on the navigation bar, then select Dock the Peek. 
To close the peek, at the top of the docked Calendar peek, click
.

When a peek is docked or not docked it only affects that view. For example, if you’re in Mail and pin the Calendar peek, when you switch to Tasks, the Calendar peek doesn’t appear. You can dock or undock the Calendar peek in each view by clicking
or
