Windows Mail Vs Outlook: Which one is better?

Windows Mail is a free app on Windows that allows you to send and receive messages from your email accounts. This app supports adding email accounts from Outlook, Office 365, Google, Yahoo, iCloud, and other accounts supporting POP or IMAP. All you need is to log into your personal account via its interface and you will start receiving or sending emails directly from here. This app comes preinstalled on Windows and you may locate it on your taskbar.

Outlook, on the other hand, is a premium email client and is generally preferred for business purposes. With this app, you also get premium support of Calendar, contacts, and other task support. Though Outlook also comes preinstalled, you need to log into your Office 365 account to use it.
