That font size may be inherent to the MS Outlook Web App.
But, try this:
1. open Microsoft Outlook Web App
2. click on the Options button at the top right
3. click on
See All Options
4. Then go to
in the left-hand drop-down menu
5. under Message Format, change the entries in
Choose Message Font:
esp. where it is probably set to '14' currently, to '10' or '11' instead.
6. click on the SAVE button at the bottom right of the window.
And then try printing email. This may be the change you need to get the correct size out of the printing process.
Let me know how it goes, please. And if the outcome is good, please take the time to rate my work and my answer, favorably. Thanks.
