How to edit or delete a Task in Planner

Planner will not let me edit or delete Tasks, even ones I created. For some reason, they are "locked." For example, I cannot change in which Plan is the Task (in case the it was entered into the wrong plan). Also, I cannot delete a task that was entered in error.

  1. How do I "unlock" Tasks?
  2. If this is not possible (either technically or administratively), can I copy, or preferably move, my Plans into a different type of Group that allows freely editing and deleting Tasks?

BTW, I use the web version of Planner; not in Teams.

Thanks.

    Hello @HMM,

    Thank you for posting your question in the Microsoft Q&A Forum!

    Before we continue troubleshooting, I’d like to gather a few details so I can better understand what might be causing the tasks to appear locked or un editable in your Planner plan. This will help ensure that I'm looking at the correct root cause and can provide the right guidance.

    • Could you please confirm which Microsoft 365 Group or Team this Planner plan belongs to?
    • Could you let me know whether the plan is using a Planner template (for example, “Basic Plan,” “Sprint Planning,” “Project Management,” etc.)? This information helps determine whether the behavior is related to a specific template configuration.
    • It would also be helpful to know whether other users in your tenant are experiencing the same issue, or if it only affects your account. If possible, please ask a colleague to try editing a task in the same plan to see whether they encounter the same limitation.

    To further narrow it down, please try creating a brand‑new Planner plan and let me know whether you are able to edit or delete tasks in that new plan. This test will help us understand if the issue is isolated to the original plan or if it is broader.

    And finally, if you receive any specific error messages or if Planner displays any warning indicators, could you please send me a screenshot of what you see? This visual detail will be extremely helpful in diagnosing the root cause.

    Once I have these pieces of information, I’ll be able to assist you more accurately and continue troubleshooting with you.

    Thank you, and I look forward to your update.

    Please understand that our initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution. 

    Kind regards,
