‘New Outlook’ coming to all Windows 10 systems next month

11th January 2025

Microsoft is getting ready to install the new Outlook email app automatically on Windows 10 systems as part of next month’s security update. The installation affects all Microsoft 365 app users.

‘New Outlook’ will sit alongside classic Outlook without changing any of your settings or preferences. Though there is no way to prevent the install on Windows 10; if you install the optional update coming on 28th January, the new Outlook app will be added to your system – but if you install the later 11th February security update, it’ll be installed automatically.

Microsoft stated:

“New Outlook exists as an installed app on the device. 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.

Currently, there isn’t a way to block the new Outlook from being installed – if you prefer not to have new Outlook show up on your organization’s devices, you can remove it after it’s installed as part of the update,”

If you do wish to remove it, this can be done uing Windows PowerShell to uninstall the app after it’s been installed.

The first preview version of the new Outlook for Windows launched in May 2022. It became available for personal accounts in September 2023 (through the 26th September Windows ‘Fall’ Update and the Microsoft Store on Windows 11) and a little later for commercial users in August 2024.
