In a move to enhance user experience and reduce the chances of accidental email sends, Outlook for iOS and Android is relocating the Send button in its mobile app. This change will take place between September 2025 and March 2026. The Send button, which was previously located at the bottom of the screen, will now be moved to the top header area in the compose view. This adjustment is aimed at minimizing accidental taps, thereby making the email sending process more deliberate and less prone to errors.

Think of this change like rearranging your office desk. If you have a stapler placed too close to your keyboard, you might accidentally knock it over while typing. By moving the stapler to a less crowded spot, you reduce the chance of such mishaps. Similarly, by moving the Send button to a less cluttered area of the screen, users are less likely to accidentally send an email before it's ready.

This update will be automatically enabled for all users of Outlook mobile on iOS and Android, and there is no need for any administrative action. It will not affect the desktop or web versions of Outlook, nor will it impact any existing add-ins, customizations, or accessibility tools. The new button placement will be consistent across different screen sizes and supported browsers, ensuring a uniform experience for all users.

Organizations are encouraged to inform their employees about this change and update any training materials to reflect the new button placement. While no issues are anticipated with custom add-ins or UI extensions, it may be prudent to test these to ensure compatibility. No compliance issues have been identified with this update, but organizations should review it in the context of their specific requirements.
