To Do Outlook Cal integration

As a leader/manager I need the ability to block time in my outlook calendar to do work (aka ToDo tasks).

I would love to be able to easily add a To Do task in my calendar. And then need the ability to move/modify the task with minimal clicks, and check them off in the calendar AND/OR in a master To Do task list.

The colors/categorization should be different To Do tasks that are not done and those that are done yet.

For people who use their calendar as the backbone of their working day, this capability would be exceptionally useful. All the pieces exist, you just need to stitch them together. This truly would be a very substantial upgrade to my daily workflow.
