Message: AADSTS50020: User account 'firstname.lastname@example.org' from identity provider 'live.com' does not exist in tenant 'Default Directory' and cannot access the application '1fec8e78-bce4-4aaf-ab1b-5451cc387264'(Microsoft Teams) 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.
