In order to permanently increase font size you should add the following string
pref("layout.css.devPixelsPerPx", "1,3"); (replace 1,3 with the desired value)
into the file
C:\Program Files\Zimbra\Zimbra Desktop\win64\prism\defaults\preferences\preferences.js
The solution works at Windows 8.1 x64 with Zimbra Desktop 7.2.7
