C Sharp :: How To Shrink Size Of Word Documents By Changing Format Settings

I've created a solution who exported Access reports (graphics/tables) to a Word- and a PDF-format. Therefor I use PDFSharp and PDFFocus.

The PDF document is okay. But the Word-document looks good. Only the size of the Word-document, it has to send by e-mail, is much too big (17MB).

I have to open the Word document again to change the PageSettings to be sure, that the page-margins and the print orientation are correct.

using System;
using Microsoft.Office.Interop.Word;  
namespace PageSetup {
    class TestPageOrientation {
        static void Main(string[] args)

[Code] .....

I don't know how it works in the Word-library source. But I've tried WdOrientation.wdOrientPortrait and once I was surprised. I saw this page in Landscape-format.

I think there is something wrong with my document sections, because the documents (with a lot of tables, graphics and a image) is much too big. And that's only after using this method.

So my next question is: How can I shrink the size of this Word document?

And what do I have to do to limit the amount of format-settings in this word-document?
