Take a look at: How to set up letterhead or some other document where you
want one header on the first page and a different header on other pages.

You may want to download the letterhead system from:

This may not be the best way to set up letterhead, but it is a way that
works for me. It consists of modular components so that changes to a
letterhead are reflected in all form documents created from then on while
documents that were created earlier remain unchanged.

Finally, take a look at the letter templates that come with Word. While they
are no great shakes as letterhead, they do use styles and AutoText lists
very well. If you use the same style names that are used in those templates
in your own letterhead for the same parts of the document, you will have
better luck with using the built-in AutoText entries in Word.
