How to get Live.com accounts working in Windows 10 Mail Preview

Having trouble configuring your Live.com, Outlook.com or Hotmail.com email address working with the Mail Preview app in Windows 10 Technical Preview builds 10061 or 10074?

Symptoms

When you try to add an account in the Windows 10 Mail Preview app, you have a few options in the Choose an account screen. 

If you select the Exchange option (which lists Exchange and Office 365 compatibility – but none of the legacy free-email domains specifically) it will ask you for your address and take a while before responding with a prompt for your password.

Shortly after entering your password, the dialog box disappears.

Solution

This seems to be an issue for people using two-factor authentication with their Microsoft Accounts.  If so, you’ll need to look up your app password – or create a new one.

After that, simply follow the same steps listed above – but instead of your normal password, use the app password.

After that, everything should work like a charm.
