If you cut and paste from a WYSIWYG editor in view mode, the links and scripts go with images, buttons, text, etc. It doesn't work if you just copy and paste the html coding from a text editor. If you do that, you just get text that is html code, displayed as html formatted text. When using Outlook to create a message in html format, Outlook is itself a WYSIWYG html editor, but with very limited capabilities - it can't view source, insert links, make tables, etc.
