Calendar integration. Add tasks and their status on a calendar.

New tasks created in Planner should also be seen in outlook

If a task is late (the due date has passed), please make sure to send a notification to both the owner and anyone related to the task (coworkers, team leader,...).

Rather than having to create every plan from scratch it would be good if the system allowed for the creation of Templates with pre-existing tasks (like in Word/Excel). This would allow a new plan and its tasks to be created from a template saving a lot of time.

It would be good if we are able to create a subtask to an existing task.

Emails consume too much time and energy. As an email user I want to only view an email once and should be able to reply/forward to a person or Outlook Group/SharePoint Site, schedule a Planner task, and/or archive the email for future reference.

OK, so working out loud is good.... to a limit. Please enable settings that reduce the very high spam content currently coming from planner. Not everyone in the group wants to know ever movement on every task. Enable users to subscribe to various types of events on tasks. Hopefully at some time there will be some consistent settings like priority etc, that can be used as user selectable alert filtering.

I want to be able to make tasks dependent on other tasks, and see them in a Gantt chart view, similar to TeamGantt.com.

We have sub consultants that we collaborate with on a daily basis. It would be nice to have different levels of permissions to view tasks, edit tasks, and / or create tasks.

Right now, groups have a 1 to 1 relationship (1 Group = 1 Plan), would be nice for a single group to have multiple plans

Ability to import and export Plan data to and from Excel, MS project, etc.

A project has a calendar, but that calendar doesn't automatically get due dates placed on it. That's pretty crucial.

A simple timeline view like SharePoint tasks to facilitate viewing the schedule

Currently you can only move Tasks to different Buckets within a Plan/Board. It would be very useful to be able to also copy or move them to different Plans/Boards that you are a member of.

Allow the creation of "Task Templates", which have a default set of properties (due one week from today, checklist items, assignment, etc.)

It would be great to have the option to make tasks created in Office 365 Tasks available in Planner

When a Task is assigned, have Planner sent the email alert in the form of an Outlook Task Request (when the request is Accepted, Deferred, etc.) and it sits in the User's Outlook Task list -- have the ability for them to update progress within MS Outlook (desktop) itself -- and let that update Planner.

(Similar features were available as far back as Outlook 2000 without a centralised server system. Now we have cloud, please bring back these features without worrying about MS Project Server / Online sales -- instead, make those "enterprise level" services...)

Most of our tasks come in via email, a simple button to convert it to a planner task would be imperative, otherwise it renders the planner a little bit pointless for us.

You can currently move a task to another bucket within the same plan but we need to ability to move or copy a task to a bucket that is in a different plan.
