Guest users should be notified by e-mail for any new assignments, due dates and late tasks. At the moment, only Members and Owners receive reminders for assigned tasks.

1. When a task is assigned to a guest, they should receive an e-mail with the information sent to their e-mail address outside of the Office 365 tenant.

2. Reminders sent to the guest's e-mail address

3. Updates to the task sent to the guest's e-mail address.

For all comments, email notifications need to be sent to all assigned to that task. That is the main use of Planner. If team members have completed their task; they can remove themselves from the assigned list, to stop the unwanted emails.

The ability to copy a Plan was recently released (see link below) but this only provides the ability to copy a plan to a new O365 Group. It does not provide the ability to copy a plan to an existing O365 Group. Most people do not want to create a new O365 Group for every Plan they have (Group sprawl). Please offer an option when copying a Plan to either target an existing Group or a new Group based on your preference.

It would be nice to be able to tag or @ people in the comments section so they get a notification.

1. Notifications to the task creator on any changes to a task's status in planner
2. Email notifications should include the plan/board that that the task is associated to or a part of
3. User should be able to @mention other users within a task
4. User should be able to create private channels within a team

If guest user adds task to my plan and I ask additional questions in comments - the guest user will need to reply somehow. I can't understand why guest comments are blocked.

A windows universal app that will run on desktops and other windows devices

It would be nice to be able to create custom status’s for your board.

We use additional status’s for when we are working on a task. For example something may be in progress but we would set the status to Waiting on Customer or Pending Testing.

It would be great to create our own status’s that can be applied to the Plan for better tracking.

The ability to add multiple checklist to a Planner Card significantly increases the flexibility of use cases for Planner Cards. Additionally, adding the ability to add due dates to each item on a checklist enhances the ability to manage the activity documented in the Card.

A task has a due date, but within the task the checklist items can also have their own due date and assigned group member to complete all needs before the actual task due date.

If someone adds a comment to a task, the person who created the task and anyone assigned to the task should receive an email notification in their inbox in the same way a person who is assigned a task receives an email notification.

Nowadays we only have 1 field to assign tasks to people.
Due some tasks being worked for several users, we need to define a single person who is accountable for that tasks but still maintaining the assignation field for people who is responsible for executing the tasks.

We as a business require the ability to have planner templates. Whenever we get a new client there is a set process to follow, so within Microsoft Teams it makes sense to create a Microsoft Planner based on a template for that specific type of client rather than having to manually create the same plan over and over and over.

TaskWorld has the ability to duplicate planners and tasks which means that you can create templates, Microsoft Planner should have the same ability.

Make it possible to appoint one task owner and multiple followers. The owner is responsible and the followers get updates made to the task.

Request: now that we can have more than one Plan per Group, it would be nice to consolidate Plans into a single Group.

Or, due to an org change, it sometimes makes sense to move a Plan to a different Group.

It would be great if individual tasks could be tagged as private (or sharing could be managed specifically rather than just sharing all tasks in a planner with all members of that planner).

I would like to manage all of my tasks on 1 plan, so it would be useful if I could add my Private tasks to a team planner then mark them as private so they can only be seen by me (or only me + my manager).

url with '&' are not recognized as correct urls...
Which is weird.

Should be able to tag a member with the @ function in a comment or a task in Planner. This would reduce the need for email correspondance.

My users track meeting tasks in Excel where each row contains the : meeting date / meeting name / issue to resolve / action to do / person to do / due date / status update

Ideally as the person running the meeting I'd like to be able to create a task for each meeting agenda item that needs it, then at the next meeting (weekly, monthly) be able to see the status of all the tasks from previous meetings so that I can make sure those assigned are doing the tasks.

Thanks for the inspiration Heather Newman :-)
