Hi Schwartz,
Good day. Thank you for reaching out, and I appreciate you sharing the details of your issue.
From my understanding, you would like to turn off the message preview in the new Outlook after the recent update. Please correct me if I am misunderstanding your request so I can assist you properly.
To turn off the message preview in the new Outlook, please follow the steps below:
- Open the new Outlook.
- Click the Settings gear icon in the top-right corner.
- Go to Mail > Layout.
- Scroll down to the Message list format.
- Uncheck Show preview text.
-

- Save changes
Once this option is unchecked, the message preview text should no longer appear in your message list.
For your references: Change how the message list is displayed in Outlook | Microsoft Support
Please try the steps above and let me know if you are still seeing the message preview afterward.
I hope this information is helpful. Should you have any further questions or need additional assistance, please feel free to share them in the comment below. I'm very happy to help.
I'm looking forward to hearing your thoughts.
