Why can't I sign in to my Microsoft account?

Question

I need the Microsoft log-in to access the BT Openreach Developer Portal, but I keep getting this error message:

Request Id: 7f5e0e5f-a875-45fc-a153-1d961feb4a00

Message: AADSTS50020: User account '[Mod Removed - PII]' from identity provider 'https://sts.windows.net/1ae15312-1062-49e1-989f-2f8a79dd5ca7/' does not exist in tenant 'BT Plc' and cannot access the application 'b79dd298-ea65-4277-af2b-f53227506860'(APP06427_DeveloperPortal_PROD) 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.

Hi @PaulJBarham, 

Thank you for reaching out to us on the Microsoft Q&A platform.  

The error message AADSTS50020 indicates a specific issue with Azure Active Directory (AAD) authentication and access control. This is an error code from Azure Active Directory that indicates an issue with user account validation or permissions. 

To rectify this problem, you must register your account as an external or guest user in the BT Plc tenancy. Please let me know if this account is already a member of the BT Plc tenant.
