Microsoft to force new Outlook app in Windows 10 with no way to block it
Lance Whitney/ZDNETMicrosoft is pushing its new Outlook app onto Windows 10 whether you want it or not.In a message sent to Microsoft 365 subscribers via the Microsoft 365 Admin Center, the company said that the new Outlook will be preinstalled on Windows 10 computers with the optional January 28, 2025, release and the February 11, 2025, security update.Once installed, the new Outlook app will replace the existing Mail and Calendar apps. After the installation, the new app will launch even if you click on the Start menu shortcuts for the older Mail and Calendar programs. Fortunately, the new Outlook will not replace the classic Outlook that comes with Microsoft 365 or Office 365 — at least not yet.Also: How to upgrade an ‘incompatible’ Windows 10 PC to Windows 11: Two ways”New Outlook exists as an installed app on the device,” Microsoft said in its message. “For instance, it can be found in the Apps section of the Start Menu. It does not replace existing (classic) Outlook or change any configurations / user defaults. Both (classic) Outlook and New Outlook for Windows can run side by side.”Though you cannot block the new Outlook from being force-installed on your Windows 10 system, you can remove it after the fact. Microsoft even provides a support page with the necessary steps for hiding or uninstalling the app if you do not want to use it individually or within your organization.The forced installation in Windows 10 is just the latest move in the gradual migration to the new Outlook. In 2022, Microsoft started testing the new version before officially rolling it out to commercial users in 2024. The new app is already preinstalled on new Windows 11 devices and versions of Windows 11 with the 23H2 update. More
