Hi IG,

Every document is based on a template (typically, Normat.dotx/m). If you create a template for your business, with the logo and company name in the header, then any document created from that template will have the logo and company name in the header.

Although you can have any of the header elements (logo/company name, or even the entire header) in the template - and, hence any derived documents - linked to external files, so that changing the content in the external files updates all the derived documents, that's generally unadvisable for the reasons given earlier.
