How can I shrink the size of Word documents by changing the 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)
        {
            var app = new Microsoft.Office.Interop.Word.Application();
            app.Visible = true;
 
            //Load Document
            Document document = app.Documents.Open(@"C:\Temp\myDocument.docx");
 
            // I've added this rows below. ...And that works
            document.Sections.First.PageSetup.Orientation = WdOrientation.wdOrientLandscape;
            document.Sections.Last.PageSetup.Orientation = WdOrientation.wdOrientLandscape;
            document.PageSetup.Orientation = WdOrientation.wdOrientLandscape;
 
            // ... and this. But the LeftMargin I can leave it.
            document.PageSetup.LeftMargin = 1.00F;
            document.Save();
        }
    }
}
 

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?

When I open the saved document and then I click on Save As, then I see that Word want to save it as a RTF-document. That could be the problem for this oversized document (22Mb).

Is there an option in the Word-component that will save your document in a Word-97-format?

Such as:

document.OptimizeForWord97 = true;
 document.DocumentFormat = WdDocumentFormat.WdWord97;
document.Save();
 

Can someone tell me the real syntax?

Thank you
