Thanks, yes, that makes the scope of what you need significantly
clearer.
First, my opinion would be that OneNote isn't the tool you need for a
situation of the complexity that I think you are describing.
One possibility would be the Task component of Outlook. That could
certainly cover relatively simple scenarios such as you describe. You
can have due dates, completed/not and so on. You could use Categories
to assign a task to different individuals.
Whether Outlook would scale to what you need I can't answer with the
information you have given.
You would probably be better asking on microsoft.public.outlook and
give a bit more detail about the scale and complexity of what you want
to do.
Or Project might be worth looking at if Outlook doesn't handle the
complexity that you need. Suitability would depend on how project
orientated these tasks are.
