I should not share my own license key, but since Microsoft Office 2003 is a very old version, people do not use this version at present. Currently, everyone uses the latest version. In that case, I have no objection to sharing the license key of this old version.

Moreover, I can conduct training through Google docs without Microsoft Office Management Training Microsoft Office software. In this case, no paid version is required. Anyone can do it for free. I will share its tutorial through the post.
