In Outlook, the default font is 11-point 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 Create, change, or customize a view.

Change the default font, color, style, and size for messages

  1. On the File tab, choose Options > Mail.

    Note: If you have Outlook 2007, choose the Tools menu, then choose Options > Mail Format.

  3. On the Personal Stationery tab, under New mail messages or Replying or forwarding messages, choose Font.

  4. In the Font box, choose the font, style, size, and color that you want to use. You can see a preview of your changes as you make them.

  • If the font that you choose isn't installed on the recipient's computer, then the recipient's mail program substitutes an available font.
