The new Outlook app for Windows 10 and 11 is a hot topic. Some users are okay with the new program, while others dislike it and even openly express how much they hate it. If you don't like the apps that replaced the old Mail app on Windows 10 and 11, there's good news: you can now go back to the old UWP app.

Users noticed that the "Try the new Outlook" toggle key has been restored to a valid state in both versions, which means that users can switch between the two applications at any time. In addition, you can run Mail and Outlook at the same time.

The new Outlook program is the default email client for Windows 1123H2 and newer. However, with the recent (and unannounced) changes, users can head to the Microsoft Store to download the legacy mail client and continue using it. It may not have more powerful features or cosmetic changes, but it's not as controversial as Outlook, whose data-mining probes forward your information to more than seven hundred "external partners."

However, the old version of the mail app is unlikely to be with us for long. Microsoft plans to completely deactivate the app on December 31, 2024. After this, users will no longer be able to download the old version of the mail client from the Microsoft Store. As Microsoft migrates users to the new Outlook application, existing versions will also stop working, and there will be some banners to "kindly" remind you after returning to the previous version.

It's unclear why Microsoft decided to go back on the road with the new email app. There is speculation that the company received so many complaints about Outlook for Windows that it decided to give users some options.
