I am running Windows 10, and would like to change the font for my emails.
I would like to change from Calibri 11 to Comic sans 12.
I want to make the change permanent.
Or, if working through an internet browser, the following works:
1. Click on the gear in the top-right (settings).
2. At the bottom of the menu, click on Options.
3. On the left of the next screen you'll see the option "message format", near the bottom of the list.
4. The font can be changed from the "message font" box.
