A family of Microsoft word processing software products for creating web, email, and print documents.
If you press ALT+F11 to access the Visual Basic Editor and then in it press CTRL+G to open the Immediate Window and in that window you type:
Application.NormalTemplate.OpenAsDocument
and press Enter, the Normal.dotm template will be opened as a document and if you then go to that option, you will see that the way in which you set that option will apply to "All New Documents" (created from the Normal.dotm template)
If your users are creating documents from other templates, you would need to set that option when you have those templates open, though in the case of templates other than the Normal.dotm template, they can be opened simply by using File>Open and the selecting the template.
