Does windows 10 mail client work on windows 7

Unfortunately, the Windows 10 Mail app is not compatible with Windows 7. The Mail app is a Universal Windows Platform (UWP) app, which means it's designed to run on Windows 10 and later versions of the operating system.

Windows 7 is an older operating system, and it doesn't support UWP apps. The Mail app is not available in the Windows Store for Windows 7, and even if you try to download it, it won't install or run on your system.

If you're using Windows 7, you'll need to stick with the built-in Windows Live Mail client (if you have it installed) or a third-party email client like Mozilla Thunderbird, Outlook, or Microsoft Outlook Express.

If you're looking for a modern email client with a similar interface to the Windows 10 Mail app, you might consider using a third-party app like Airmail, eM Client, or Spark. These apps are available for Windows 7 and offer many of the same features as the Windows 10 Mail app.
