If you’re using the Mail app on the Surface Pro or RT for several accounts ,you might want to make a separate tile on the start screen for each one. This is handy if you want to quickly a specific account without having to find it in the Mail app.
First you’ll need to add multiple accounts to the Mail app. Then launch the Windows 8 Mail app and open one of your accounts.
Swipe from the top of the screen down and select Pin to Start from the toolbar. Then give the account tile a name and tap and pin it to the start screen.
That’s all there is to it. In this example I grouped my email account tiles for easier access.
