Entra ID Self Service Sign-up: How to debug why it doesn't work for a particular tenant?

Question

Hi,

I setup Self Service Sign up as per this article.

https://learn.microsoft.com/en-gb/entra/external-id/self-service-sign-up-overview?WT.mc_id=Portal-Microsoft_AAD_IAM

Sign Up works great with another Entra ID tenant I created and with Google. However, when I try to sign up with an account from my company's Entra ID tenant, I get redirected back to the sign in page with the error message "This account does not exist in this organization" at the end of the sign up flow after authenticating into my company's tenant. What could be wrong and how can I prove the root cause of the problem?

I looked at all the Entra ID sign in, audit, and provisioning logs but there's no entries directly correlated to the time of the failed sign in attempt. I suspect that my company's tenant has restrictions on the External Identities outbound access settings but I can't verify that since I don't have admin access to that tenant. Is there a way to determine if that is why I get that error?

Thanks in advance!

Hi @Jason Lee

Thank you for reaching us!

I understand that you have setup Self Service Sign up when you are using the flow it is not allowing you with Entra ID account.

It might be cause of this error is using the incorrect sign-in URL. For example, if you use https://login.Microsoftonline.com/<YourTenantNameOrID> URL, the authentication is expected to be run on your tenant only. That’s why users in other organizations cannot access the application. Use the corresponding sign-in URL for a specific type of application.
The other side could you please check capabilities as per below document.
