The Lumia 2520 is based on Windows RT which comes supplied with a Mail app and a free copy of your favorite Microsoft Office applications, including Outlook.
With the Mail app, you can add all your accounts like Gmail, Yahoo!, Outlook.com, and even your work email. If you currently use an app like Windows Live Mail or Outlook Express, try the Mail app.
For the heavier email user, you will be happy to hear that Outlook is the same on Windows RT as the Outlook 2013 at your office. It's easy to manage your work email, calendars and task lists.
