The location of the search bar in Microsoft 365 Word, Excel and PowerPoint often makes simply clicking and dragging the application windows difficult, at least for me. Many times I end up click within the search field instead of the tiny space between for the drag and drop operation.

This article will show you what setting to adjust to hide the Search Bar from the Word, Excel and PowerPoint title bar. Note, this will not actually remove the Search bar. Rather, it will simply shrink or collapse it down to just a magnifying glass icon. You can also press Alt+Q to bring up the full search bar or use the keyboard shortcut Ctrl+F to navigate and search through your document.

Regarding Outlook 365; As of this post (2023 October), it is not possible to collapse or shrink the search box (which is used to search email) in Outlook 365, Outlook and Word are two different applications and some features are not the same.
