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.

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.

While support will end for Office apps on Windows 10 in October, it doesn’t mean the apps will suddenly stop working. Microsoft notes in a support document that was updated in D

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.

Microsoft announced last year that it would be retiring the Windows Mail & Calendar apps in favor of the new Outlook at the end of 2024. As of January 1, these apps are no longer functional and will refuse to send or receive any more emails.

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.
