timosec Same! I had assumed this was going to be one of the new features because I thought the reason this didn't work before was because Flagged emails went to Tasks, which was separate from Planner. Absolutely maddening that they did this whole update claiming to integrate Outlook/Tasks/Planner only to find that in reality it is still very disjointed. Our staff is (unfortunately) very dependent on email, and that's how our department gets most of our requests, so the ability to easily create Planner tasks from Outlook emails is critical for us.
I know there is a way to do this using Power Automate, but it's confusing and clunky to set up and just frustrating that we need so many extra steps for something that should work out of the box. I might as well just keep using Trello (which has a similar automation tool) or Zapier.
Microsoft, please address this!!!
