Letter icon on bottom of lock screen

Wondering what the icon on the bottom of my lock screen is and how I can clear it. I have no new messages and no new yahoo emails (the only email service I use on my phone).

Picture of the icon in question has been attached.

That is an icon for Hotmail. You might have received an email from Microsoft since you need a Microsoft account to run Windows Phone and the emails from Microsoft would come to the linked account - most likely Hotmail.

Yup, was an email from bing rewards. Thank you very much.
