A family of Microsoft word processing software products for creating web, email, and print documents.
Horizontal scrolling is automatically invoked by macOS based on the Zoom percentage. Word has no control over that behavior. Neither have I seen any System Setting to disable it. However, the only time I see it occur in most programs (including Word) is when explicitly using the Horizontal Scroll Bar, dragging to the edge of the window, or using a 2- or 3-finger swipe on the trackpad [or mouse equivalent].
Since your experience seems to be different please provide the following information:
- Office Version Number as indicated in Word> About Microsoft Word
- macOS Version Number as shown in **> About This Mac**
- Whether using Modern Comments or Legacy Comments
- Any additional descriptive detail re exactly what triggers the horizontal scrolling
Also, please understand that you are not communicating with anyone from Microsoft here. Neither do the contributors have any control over the product Microsoft provides. The forum is hosted by Microsoft but nobody from Microsoft design/development monitors the messages. If there is a suspected issue with the software the best avenue is to use Help> Feedback in the menu bar of the respective program. Alternatively, use this link to the Feedback site where you can post suggestions, feature requests, or complaints: Word · Feedback Don't expect a personal reply but that is the venue read & evaluated by those who can act on it.
