Is it possible to have different default style when typing e-mail and when writing documents

[Harald]

I am using Word as editor for Outlook 2000 and 2003. When I write an e-mail
I want a different default stile compared to when I start writing a "normal"
document in Word.

Question: Is it possible to configure Word to have one default stile when
writing documents, and another default stile when typing e-mail. Word must
automatically select correct style depending on typing e-mail or normal
document.

Thanks in advance

Harald
