Change the default font or text colour for email messages

Applies to: Outlook for Office 365, Outlook 2019, Outlook 2016, Outlook 2013, Outlook 2010.

In Outlook, the standard font is 11-point Calibri in black. It’s used when you create new email messages. You can edit the default font along with its colour, size, and style — such as bold or italic.

Outlook enables you to adjust the font, colour, size, and style for new messages and replies and forwards separately. If you want to alter the font used in the message list, see Create, change, or customise a view.
