Hi,
if Entourage is not listed, click on Select… in the dropdown menu in
Mail's General preferences; this will allow you to navigate to the
Entourage application and select it as your default application.
The best solution for sending a newsletter as the body of an e-mail,
especially given the tools you own (Microsoft Office 2004), is the
combination of Word and Entourage, as described in my earlier post.
However, this is not how I would go about it.
First of all, HTML e-mail messages are generally frowned upon, as they
eat up a lot of bandwidth, and there is no way to predict if the result
which the recipients will see is identical to the newsletter you have on
your screen. HTML messages can change depending on the recipient's
preferences, or the fonts installed on his system, or even his web
browser or e-mail application, so the result is never reallly reliable.
I would recommend two solutions:
1) creating the newsletter on a webpage via iWeb, for instance, and then
simply sending the link to the webpage via e-mail.
2) creating the newsletter in Word, saving the file as a PDF and then
attach the PDF file to an e-mail message. The advantage of that method
is that the final result (i.e. the newsletter PDF) will look exactly the
same on any platform.
Hope this helps!
