A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
Just found a new way. Did not fully test it yet but to my surprise it seems to work:
Create your template notebook on OneDrive
In the Web frontent (using your browser) copy the notebook file to another location or to the same folder (a (1) will be added to the name then)
Although that "file" ist just a symbolic link to hidden real ONE files those seem to be recreated/copied as well
So you can just rename the new copy and get a notebook which structure and content is based on the original one.
As I said: not fully tested yet but i can see no drawbacks up to now.
