Windows 7: How do I change font size in Windows Live Mail?

I hate that the menu bar has been replaced by ribbons in Windows Live Mail. The only way I know how to change the font size of the messages in my Inbox home screen is to go to Tools > Options, which I cannot do because I don't know how to access the Tools menu without a menu bar. Please tell me how to view/change my options with this new ribbons system. Thanks so much.

Hi Tracy,

Click the nameless blue button on the left hand side of the ribbon.
Click Options.
Click Mail...
Activate the Compose tab.
Click Font Settings... to the right of Mail.
You can set the default font, font style, font size and font color here.
Click OK twice.
