From the top bar menu, select Mail and click Add Account.Setting up a Microsoft email account (Hotmail, Outlook, Live, or MSN) using the built-in macOS Mail app is a really easy process. Note that these instructions have been written for Hotmail, but the process is exactly the same whether you want to set up an Outlook, Live, or MSN account. In this tutorial, I’ll show you how to set up your Microsoft email account (Hotmail, Outlook, Live, or MSN) using the built-in macOS Mail app. But you may prefer to use the built-in macOS Mail app for all your email accounts, like I do. To have an access to your Microsoft’s email account from your Apple MacBook (any), iMac, Mac mini, or Mac Pro you can use the Microsoft Outlook app available from the Apple’s App Store.
