I'm having the same issue. This solution works well, but I'd like to switch the default tasks folder to Toodledo so I don't have to click through to it every time I go from Mail or Calendar to tasks.
Also, how do you save your sort preferences in this outlook view? Every time I go into my task list I have to reset the sort to alphabetical. It doesn't save my preference like it does on the mobile app or on the website.
