Question details

The user needs to share a specific Microsoft Planner task with an external worker who does not have a Microsoft 365 license.

How to Share a Microsoft Planner Task with an External User

Product: Microsoft Planner
Device & OS: not provided
Scenario: Collaborating with external contractors or freelancers who need access to project tasks but do not possess an organizational account.
Observed behavior: Microsoft Planner does not support sharing a single task directly with an external user; it requires assigning group-level access.

Before you start

Ensure that your organization's IT administrator has enabled guest access for Microsoft 365 Groups and Planner in the admin center, as external sharing will not work otherwise.

Solution 1Recommended

Add the External User as a Guest to the Planner Plan

Since Microsoft Planner cannot share individual tasks, you must add the external user as a guest to the entire plan. This allows them to view and collaborate on assigned tasks without needing a paid license.

Microsoft Planner manages permissions through Microsoft 365 Groups. Therefore, granting access to a task requires granting guest access to the group connected to the plan.

Open your Microsoft Planner

Log in to your Microsoft 365 account, navigate to Planner, and open the specific plan that contains the task you want to share.

Access the Members list

Click on the 'Members' dropdown located at the top right corner of the Planner board.

Invite the external user

Type the full email address of the external worker. Select 'Add as guest' from the dropdown prompt to send them an invitation.

Assign the task

Once added, open the specific task card, click 'Assign', and select the newly added guest user. They will receive an email notification with a link to access the task.

Add the External User as a Guest to the Planner Plan

Guest Account Setup: The external user will receive an invitation email. They may be prompted to create a free Microsoft account using their existing email address to authenticate and access the Planner board.

Frequently Asked Questions

Can I assign a Microsoft Planner task to someone outside my organization?

Yes, but they must first be added as a guest to the Microsoft 365 Group associated with the plan. You cannot directly assign a task to an external email address without this step.

Do external users need a paid Microsoft 365 license to use Planner?

No, external users can access and collaborate on Planner boards as guests without needing a paid Microsoft 365 license, provided your organization allows guest access.

Is there a way to export a single Planner task to share it via email?

Planner does not have a native feature to export a single task. However, you can export the entire plan to Excel and share the spreadsheet, or manually copy the task details and paste them into an email or a document to share with the external user.
