Add guest user without license to Power Platform / Copilot Studio environment

Posted on by CU24070943-1

Hello,

I would like to add an external contractor to our Power Platform environment (for a Copilot Studio project) as a guest user via Azure AD (B2B).

She has accepted the invitation and appears in our directory as an active guest.

However, when I try to add her to the environment from the Power Platform Admin Center, she does not appear in the list of available users — likely because she does not have a Microsoft 365 license assigned.

According to Microsoft’s official documentation, a guest user without a license can still be added to a Power Platform environment and assigned a role such as Environment Maker, as long as the permissions are explicitly granted.

My questions are:

How can I add a guest user without a license to a Power Platform environment and assign her the necessary permissions to access Copilot Studio, if she doesn’t appear in the user list?
Does this user need a Copilot (or Microsoft 365) license to access Copilot Studio and work on creating an agent, or can she do so using access provided through our tenant, without a dedicated license?

Thank you in advance for your help in resolving this issue.

Hi @CU24070943-1,

Here's my responses, I hope this helps you keep going!

Power Platform only lists users who have accessed a resource in the environment or have been assigned a role. If she hasn’t accessed any apps or been explicitly granted a role, she won’t appear in the Power Platform Admin Center user list.

Assign a license to the guest user

In your tenant (Azure AD):

Assign a Power Apps Per User, Power Automate Per User, or Copilot Studio license. A trial license works too (for up to 30 days). Force user to sign in once (optional but helpful)

Ask the guest to:

Go to powerapps and switch to your environment from the environment switcher. This helps register them in the environment.

She will need one of the following licenses:

Copilot Studio license

Power Apps Premium license (includes Maker capabilities)

Power Automate Premium (if agent uses flows)

Power Platform Developer Plan (only in their own tenant — not usable in B2B scenarios)

Hello CU24070943-1,

Here’s a quick guide on how to grant Copilot Studio access to a guest user (without assigning a Microsoft 365 license):

Guest User is Active:

Ensure the guest has accepted your Azure AD invitation and appears in your directory.

Add to Power Platform Environment:

Ask the guest to sign in directly to the environment URL, this will trigger just-in-time (JIT) access provisioning, and the user will start appearing in the user list.

Assign Permissions:

Go to Power Platform Admin Center

Navigate to your environment > Settings > Users

Add the guest's email manually

Assign the Environment Maker role (or another role as appropriate)

Licensing Requirements:

The guest does need a Copilot Studio User License it’s free and can be assigned via Microsoft Admin Center

A Microsoft 365 license is not required for Copilot Studio access if they're working within your tenant

Please review the steps above, I hope this helps resolve the issue and enables your guest user to start building agents in Copilot Studio smoothly!
