Users want to create or share a Microsoft Project within a shared Microsoft Teams channel that includes external users who are not guests.

How to Add Microsoft Project to a Shared Teams Channel with External Users

Product: Microsoft Teams / Microsoft Project
Device & OS: not provided
Scenario: Collaborating on a project timeline and tasks within a Teams shared channel that involves external partners or clients.
Observed behavior: Users need to know the steps to add a Project tab and understand whether external users will successfully inherit permissions to view or edit the project.

Before you start

Ensure you have the appropriate permissions to add new tabs to the Teams channel, and verify with your IT administrator if sharing integrated apps with external users is permitted by your organization's policies.

Add Microsoft Project as a Channel Tab

You can use the native tab functionality in Microsoft Teams to pin a Project or Roadmap to the shared channel.

While adding a Project tab to a standard channel is straightforward, shared channels have strict cross-tenant permission boundaries. External users who are not added as guests in your Azure Active Directory may face access issues due to Microsoft's underlying group permission design.

Navigate to the shared channel

Open Microsoft Teams and go to the specific shared channel where you want to add the project.

Add a new tab

Click the '+' (Add a tab) button located at the top of the channel's interface.

Select the Project app

Search for and select 'Project' (or 'Roadmap') from the list of available applications.

Configure the project

Choose to create a new project or select an existing one from your available lists.

Save and pin

Click 'Save' to add the project as a tab in the channel for your team members to access.

Permission Limitations: Even after adding the tab, external users who are not guests in your tenant might still be unable to view or edit the Project tab due to Microsoft's current shared channel limitations.

Frequently Asked Questions

Why can't external users see the Microsoft Project tab in a shared channel?

Microsoft Project permissions are closely tied to Microsoft 365 Groups. External users in shared channels (via B2B direct connect) do not get added to the underlying Microsoft 365 Group, which prevents them from accessing apps like Planner and Project.

Can I share a Microsoft Project with users outside my organization?

Yes, but you typically need to invite them as guests in your Azure Active Directory (B2B collaboration) and assign them appropriate licenses or permissions. Standard shared channel external access is usually insufficient.

Is there a workaround for sharing project timelines with external users in Teams?

A reliable workaround is to export your project timeline to a PDF or an Excel spreadsheet and upload it to the 'Files' tab of the shared channel. The Files tab relies on SharePoint permissions, which work seamlessly for shared channel external users.
