This tutorial explains how to open an email in new window in Windows 10 Mail app. By default, whenever we click on a mail using Mail app of Windows 10, it opens within the Mail app. However, there is a built-in option in Mail app using which you detach any email from Mail app and then open it in a separate window. This way, you can read a mail in full screen mode or have more space to read a particular email. You can also open multiple emails in separate windows.
This feature is available for Outlook, Gmail, and all other accounts that can be used in Mail app of Windows 10.
In the screenshot above, you can clearly see that an email is opened in a separate window and Mail app is visible behind that window. Once an email is opened in a new window, you can use Mail app as usual. So new mail window won’t interrupt with Mail app and vice versa.

Windows 10 Mail app doesn’t provide any option to hide email list so that we can have more space to read a particular email. We can shrink left sidebar of course, but still it doesn’t give much space. Also, we can hide message preview in email list, but can’t hide or shrink email list. So when you have the need to open an email with more space while using Mail app, then you can simply use the native option and read any email in a new window.
