Open Outlook Express. Along the top of the screen on the left-hand side you will see "File", "Edit", "View", "Tools", etc.
Click on "View" and from the drop-down menu highlight "Text Size".
Another drop-down menu will appear where you can choose from five text sizes. Mine is set to "Medium".
I only have an old version of Outlook Express but in Tools>Options there is a compose tab in which you can set the default font size for new message creation. I would have thought that there would be something similar in Outlook itself.
I use Outlook Express and Windows XP.
When you get onto Outlook Express "Send" go to VIEW and select "Tool Bars", then tick "Formating bar" which gives you a choice of font type and size
Well, that's what I have on mine
Fab! Thanks Cath. It wasn't that, but while there I had a look around and under "Tools" there was a tab "Options" and "Compose" so I clicked on that. You can change the font size there, and even change the style of font. Mine was set to size 14 so I've changed it to 10.
It's been driving me mad for a long time now. Thanks so much.
