Poor font rendering..

Perhaps the gamma adjustment is different ?
FX should pick this up from the

I don't know what Outlook (*) uses if its a WPF app then maybe its picking
up an over-ridden setting for this from the registry :
You should be able to check that out fairly easily,and you can use this
JDK app to see what the SystemParameterInfo setting is.

import java.awt.*;
import java.util.*;
public class GetGamma {
   public static void main(String args[]) {
      Toolkit tk = Toolkit.getDefaultToolkit();
      Map map = (Map)tk.getDesktopProperty("awt.font.desktophints");
      if (map != null) {
       for (Object k : map.keySet()) {
             System.out.println(k + " : "  + map.get(k));

C:\>c:\jdk1.8\bin\java GetGamma
Text-specific antialiasing enable key : LCD HRGB antialiasing text mode
Text-specific LCD contrast key : 120

(*) I'm sure Outlook used to be a GDI app, but who knows what version 
you are using
and what rendering technology it uses.
I've tried to make the point many times before that someone can always 
point to
a difference from 'native' rendering simply because the platforms like 
OS X and Windows
have multiple rasterisers and multiple font technologies all of which 
are different
from each other.  So whilst any notably 'poor' rendering needs to be 
looked into
it maybe sometimes an artifact of one rendering path compared to another ..
