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

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.

You only have a few weeks before the new Outlook is forced onto your Windows 10 PC. The new Outlook will arrive automatically with an optional Windows 10 release that will ship on January 28, 2025. The app will then roll out to all Windows 10 PCs as part of the monthly security release to Windows 10 that will become available on February 11, 2025.

Microsoft will force install the new Outlook email client on Windows 10 systems starting with next month's security update.

Microsoft decided to force install the new Outlook on Windows 10 starting with the new updates of the OS. You can quickly uninstall it after.

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.

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 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.
