Jump to Font type and colors - The size and color of a few Outlook sections and elements can be. Changing the font size and color is not possible.
NOTE: Even if you closed Outlook when another module was active, such as Calendar or Tasks, Outlook opens by default with the Mail module active. Click the View Settings button in the Current View section of the View tab. On the Advanced View Settings dialog box, click Conditional Formatting. On the Conditional Formatting dialog box, click Add to add a new rule. Enter a name for the new rule, such as “List Font Size,” in the Name edit box and then click Font.

Change the Font, Font style, and Size, and select other settings such as Effects and Color, as desired. Click OK when you have made your changes. Because we are applying the same font to all parts of the message list (sender’s name, subject, date received, and size of each message), we are not specifying a condition.
A dialog box displays, warning you of that fact. The font for all parts of each message in the message list (except for the excerpt of the message text) is changed to the font and size (and other font settings) you selected.
You can delete the rule you created to go back to the default settings, or you can deselect it in the list of Rules for this view on the Conditional Formatting dialog box.
