Dear Dave Jackson2
Welcome to Microsoft Community.
Hi, I am sorry to hear that you are experiencing some confusion when using new Outlook.
Search in New Outlook is not a ribbon item that can be added or removed. It's a search bar, usually located at the top of the new Outlook window. You can search your e-mail, contacts, and files in one place; just type what you want to find in the search bar and press Enter on your keyboard and that's it. :)
I sincerely hope that this can solve your problem. If you have found anything else worth mentioning, please contact me and tell me about it, I would be happy to solve the problem with you, thank you for your cooperation and understanding. :)
Best regards
