Designed to replace the current Mail and Calendar apps, the new Outlook can only be removed after it's been installed.

As the push toward Windows 11 continues, Microsoft confirms that Windows 10 users will lose support for apps including Word, Excel, and Outlook.

Microsoft will start automatically installing its new Outlook email app on Windows 10 devices. It's already pre-installed on most Windows 11 PCs and rolled out to some existing Windows 11 systems.

Starting next month, Microsoft will begin forcibly installing its new Outlook email client on all Windows 10 devices. This move will occur in two phases. The first phase of the rollout will begin on 28 th January 2025 with the release of an optional Windows 10 update. This update will include the new Outlook for users who choose to install it.

Microsoft 365 apps will continue to function after the Windows 10 end of support date, but there could be issues over time.

The good news is that the February update which brings the new Outlook doesn't strip out the old version of the app, so you can still use that.

Microsoft will automatically install its new Outlook client on Windows 10 PCs with next month’s Patch Tuesday update.

The new Outlook will be automatically delivered to all computers running Windows 10. It is the same version of the program already installed in Windows 11, provided users continually download all updates.

For several months now, Microsoft has been urging Windows users to switch over to the new Outlook app, with classic Outlook recently getting an official “death date”. Many aren’t happy about this, holding off on jumping ship as long as they can — but the clock is ticking down.
