Windows 10 has a built in Mail App that allows you to connect to any email accounts you have on services such as Outlook.com, Exchange, Office 365, Yahoo! Mail, Gmail, POP3 and IMAP accounts.
While it is not a fully featured email program like Outlook, it is very capable of providing most users easy access to their email and provides straight forward folder management for accounts and some other advanced settings.
One of those advanced settings allows a user to select how much of their email they want to sync down onto their device. This can be very handy because of the varied storage capabilities between desktops and tablets.
This how to will show you the sync settings and how to adjust the amount of email you are synching on each of your devices. This setting can be adjusted for each email account allowing you maximum flexibility.
