Microsoft Teams is designed as an enterprise collaboration tool and is part of Microsoft 365. As a result, Teams functionality—and specifically, the Teams-related permissions in Microsoft Graph—are only available to work or school (organizational) accounts. Here are some key points to understand:
- Teams APIs and permissions are supported only for Azure Active Directory (work or school) accounts. Personal Microsoft accounts (like those from outlook.com or hotmail.com) do not have a Teams license or the organizational context required to use those APIs.
- Even though you can sign in with a personal account and consent to basic permissions (for example, for other Microsoft Graph endpoints that support personal accounts), the Teams-specific endpoints and permissions are not applicable. This isn’t an issue with your app registration or the consent process—it’s a limitation by design.
- Admin Consent for your App Registration in Azure applies to organizational accounts within a tenant. Since personal Microsoft accounts aren’t managed in an Azure AD tenant in the same way, they can’t grant admin consent for Teams-related permissions
