Message: AADSTS50020: User account 'alexhark05@Stuff .com' from identity provider 'live.com' does not exist in tenant 'Microsoft' and cannot access the application '030083e3-f390-4125-b928-e548fd1bb965'(Minecraft Education Edition) 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.
What's the solution?
