Administrators can set a block policy on users to stop them deleting Planner tasks that they didn’t create. The feature isn’t well known, but might be useful in situations where plan owners want tight control over task deletion. Unfortunately, the implementation isn’t well finished and client user experiences are not what you’d like.
A new feature allows Teams users to create tasks from personal chats and channel conversations. Tasks from chats are personal while those created from channel conversations can be personal or go into a Planner plan. Although you might like the tasks to be populated more fully, the overall implementation is a nice addition to the Microsoft 365 tasks system.
Microsoft To-Do now boasts the ability to process messages flagged by Outlook as tasks. It’s a great way to handle complex tasks that arrive in email, so Office 365 users might like to give To-Do a second look. The steps feature makes it very easy to build checklists of stuff that needs to be done to accomplish tasks.
