Yes. I also use Outlook and have noticed that it will do that. But another thing I am confused about is setting the font size- In Outlook, messages set at size 14 outgoing are good and very readable, but when I use 14 in Apple Mail, it's tiny. I usually compose emails in a word processing app such as Bear Notes and then copy and paste the text into either Outlook or Apple Mail. I just never know which size to choose for Apple Mail. If I choose 18, it's on the smaller side, but if I choose the next higher number when hitting Command T it jumps to size 24 which is gigantic.
