Group by Category disappeared

toleanne Thanks for the feedback.  I can't really figure out how to do what you're saying.  To get the ToDo bar in my Outlook Desktop, I have to flip the switch that says "Try the new Outlook".  But when I do that and hit the ToDo bar it just opens up ToDo on the web.  When I select Tasks on the left site menu there is no option to Arrange By.  There is a Sort button on the upper right, but that doesn't have 

But I'm guessing this solution would not allow me to share the task list with others and have them be able to sort it by Category.  The only reason I was using ToDo was because you can share the list.  Unfortunately, without Group by Category, it's useless to me.  I feel like the feature was added recently and then deleted recently.  I sure hope MS is planning to bring it back.
