how to change font size in hotmail using tablet/outlook?

[sawa]

Hi.
Using basic internet Microsoft sign in for hotmail-( outlook) , NOT a tablet application ( they worked terribly)---but need to know:

IS THERE ANY WAY TO CHANGE THE SIZE OF THE FONT IN TYPING OUTGOING EMAILS?!
am using Google nexus 7 tablet...
The Hotmail works fine---but I don't see any options for font size.

Thanks a lot!
