Hi! I have been able to make the font larger in the EMAILS (but not elsewhere) as follows.... Click on "tools," then "preferences." You should be in "general" preferences at this point. If not, click on the thing in the left bar that says "general." Scroll down to "Language & Appearance." You should be able to change the font size there. I don't know how to make the font larger everywhere else. But maybe this will be of some help in the mean time or in case no one answers your question.
