The Mail and Calendar apps on Windows 10 provide a basic, touch-friendly email and calendar application that is great for use with personal email services, and comes free with every Windows 10 device.

Send messages are also stored on the server, as is information about which messages have been read. In the end, IMAP is a much better protocol to use if you’re connecting to your mail server from multiple devices. And in a world where people have become accustomed to checking mail from their PCs, phones, and tablets, that’s a vital distinction.

Outlook 2013 and Outlook 2016 also are available for Windows 10 devices, with the purchase of Office 2013, Office 2016, or Office 365. Outlook 2013 and Outlook 2016 are the leading applications for professional email, calendar, contacts, and task management, for those who want the richest feature set for email and calendaring.
