How to stop Mail app switching to New Outlook in Windows?

Issue: I don't want to use the New Outlook instead of the convenient Mail app. New Outlook is overloaded with things I don't need and simply feels bad, so I want to keep using the Mail app. How do I do this?

Solved Answer

On the official page of the New Outlook, Microsoft promises users to “bring the latest features, intelligent assisted capabilities and a new modern and simplified design to your Outlook app.” However, not all people like change and they are content with what is already there – including the Mail app.

Mail app was a great addition to the latest Windows versions such as Windows 10, as it allows users to compile all email accounts into one place. It has a neat and simple interface, which many people prefer.

The New Outlook app was first introduced in 2022, and in 2023 started slowly transitioning people to use it; i.e., users one day turned on their PCs, clicked the Mail app, and saw the New Outlook instead. Many people found it pretty intrusive, as they never accepted or asked for the change.

Luckily, there is an easy way to go back to the Mail app – all you need to do is click a switch located at the top-right corner of the window. While this method works for users, they noticed that the Mail app keeps eventually switching to New Outlook continually, and would like a more permanent solution. To go back, users once again are asked to provide feedback, which if they don't want to do, have to select the box, making it into a several-step process.

While it is impossible to completely fix the issue where the Mail app is switching to Outlook, there are a few workarounds available. Please check out the instructions below. We also recommend using a powerful PC repair and maintenance utility FortectMac Washing Machine X9 when facing various Windows issues.

Protect your online privacy with a VPN client

A VPN is crucial when it comes to user privacy. Online trackers such as cookies can not only be used by social media platforms and other websites but also your Internet Service Provider and the government. Even if you apply the most secure settings via your web browser, you can still be tracked via apps that are connected to the internet. Besides, privacy-focused browsers like Tor is are not an optimal choice due to diminished connection speeds. The best solution for your ultimate privacy is Private Internet Access – be anonymous and secure online.
