In Outlook, the default font is Calibri in black. It's used when you compose new email messages. You can change the default font and its color, size, and style — such as bold or italic.
Outlook allows you to change the font, color, size, and style for new messages and replies and forwards independently. If you want to change the font used in the message list, see Change the font or font size in the message list.
