Tasks not supported in W10M Outlook Calendar?

I did not install any insider build of Win10 Mobile and today I found that my favourite feature of managing tasks is not supported anymore in "Outlook Calendar" of Windows 10 Mobile.

Have I missed anything? Possible to get this feature back?

Keeping track of "events" is not enough. I need to keep track of my tasks which have deadlines. Tasks are different in nature with events that it is not meaningful to create a new "event" to represent a new "task"....

I totally agree

I am also missing this essential feature of Exchange and reported it months ago in the feedback app - without success. I have no idea how this OS should match professional needs when such things are laid off in favor of toys like "personal assistants".
