Can external B2B guest accounts be assigned a Copilot license to access a SharePoint Copilot agent??

Question

We have a SharePoint-based Microsoft 365 Copilot agent that external contractors need to access. The contractors are set up as B2B guest accounts in our tenant and can access the SharePoint site, but when they try to use the Copilot agent they get a "no license" error.

We understand the agent requires a Copilot license assigned within our tenant. Can Copilot licenses be assigned to B2B guest accounts, or do we need to create internal member accounts instead? We're looking at ~30 users across multiple sites.

Hello Cindy Zhang

Microsoft 365 Copilot licenses cannot be assigned to B2B guest users. Copilot requires a licensed user within the tenant, and guest accounts are not eligible for license assignment.

• Create internal member accounts for those users in your tenant and assign Copilot licenses, OR
• Have users access Copilot from their own tenant where they are licensed (if applicable)

B2B guest users can access SharePoint content, but cannot use Copilot features. To use a SharePoint Copilot agent, users must be licensed member users in the tenant.

Create member accounts in your tenant and assign licenses. Guest accounts will not work for Copilot.
