About syncing MS Teams (Online Meetings)

Greetings,

I have question on syncing MS Teams.

We are trying to use Online Meeting by syncing MS Teams to our product and we found that Online Meetings API isn’t supporting personal account.

So, we build our app as multi-tenant but we are currently getting error code AADSTS50020 (Not registered by administrator)

Is there anyway can client register themselves not by administrator?

Thank you for all the comments and helps.

Hi @flowdev1-9949

Are there any other error messages when you receiving this error code?

According to your error code, this issue seems related to Azure AD login error. When user is trying to sign up with a live.com ID which is not a Windows Azure native org account, it will cause this issue. For more details about this error, you can refer to:

Considering your issue is also related to Teams api development, I will also add teams-app-dev tag to your thread. Someone checking office-teams-app-dev tag will give you more insights. Thanks for your understanding.

Error Message :

AADSTS50020: User account '${another_user_id}' from identity provider 'live.com' does not exist in tenant '${app_tenant}' and cannot access the application '${app_tenant_id}'(app_service_name) in that tenant. The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account.

According to your description, the account types is set to Multiple tenant. However, if your authentication is for specific tenant i.e., https://login.microsoftonline.com/your_tenant_name_or_id, users from other organizations won't be able to access the application and are required to be added as guests in the tenant specified in the request.
