Removing an account
To see emails from different accounts in the Mail app, you need to add them.
On Start, tap or click Mail.
Swipe in from the right edge of the screen, then tap Settings.(If you're using a mouse, point to the bottom-right corner of the screen, move the mouse pointer up, then click Settings.)
Tap or click Accounts.
Tap or click Add an account, choose the type of account you want to add, then follow the on-screen instructions.
The Mail app doesn't support email accounts that use POP (Post Office Protocol). To get these accounts in Mail, see Using email accounts over POP on Windows 8.1 and Windows RT 8.1.
The Mail and People apps work together, so if you've added an Outlook.com or Exchange account, your contacts are automatically added to the People app. For all other accounts, you need to add the same accounts to the People app to get your contacts, just like you did in the Mail app. See how to do that in the "Adding or importing contacts" section of People app help.
