Message: AADSTS50020: User account 'xxxxxx.xmail.com' from identity provider 'live.com'
does not exist in tenant 'Microsoft Services' and cannot access the application
'b9c392b1-7049-4d6c-86bf-9bb91214900d'(Microsoft Learning Identity Service) 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.
