Sick of Calibri? You don’t have to stick with Office 365’s standard set of fonts in your documents or messages. It’s a snap to change the font of an individual email message or even the default font for all new email messages you create.

In individual messages, simply highlight the text you wish to change, and select a new font style from the menu. See the image below.
