Don’t use Times New Roman as “fall back” font

Several mail applications and web mail services do not actually specify a font when composing and sending a message in HTML format. So although the sender thinks that he/she is sending a message in the Arial format, it actually arrives in Times New Roman on my computer.

This is of course because Outlook uses Times New Roman as the default font when none is specified.

Is there any way that I can change this default font to something different than 12pt Times New Roman? For instance, 10pt Arial?

Font buttonIf no font has been specified in the message, Outlook will fall back to 12pt Times New Roman by default.

You can change this default, but how and where you must change it depends on your version of Outlook and whether or not you have the same version of Word installed as well.

Method 1: Changing the settings in Word

  1. Open the Options dialog in Word

  3. Scroll down to the “General” option group and click on; Web Options…
  4. Select the Fonts tab.

  6. Change the “Proportional font” setting at the bottom from Times New Roman with size 12 to the font and size of your choice. For instance Arial with a size of 10 or Calibri with a size of 11.
    The “Fixed-width font” settings is used to display specific HTML tags which are often used to display code samples in a message.
