Format text defaulting to Auto

[JohnDohe]

Whenever I'm in a browser and click to email a link
to someone, Outlook 2010 opens a window to send
a new email, like it should.



The link is in the body area of the email (where you
type your actual email message) also like it should be.

But when start typing my email message, and hit the
enter key to start a new line, the cursor jumps two lines
... as if I'd hit the enter key twice instead of the just once
that I did.

I have to do a Ctrl-A to select the entire document, click,
Format Text > Paragraph > "Show the Paragraph Dialog Box" > Indents and Spacing
to find that the "Spacing" setting is set to "Auto" for both
the "Before" and "After" settings:

I click to change the "Before" and "After" settings to "0 pt":

and the double line spacing reverts to single.

But ... this is such a hassle!

How can I set the default to be "0 pt" for the "Spacing" setting
whenever I email a link from my browser?

BTW this happens no matter what browser I'm using:
Chrome, Firefox and Internet Explorer.

Thanks!
