Getting “That Microsoft account doesn’t exist” for Microsoft logins on Auth0?

Question

Hi all,

I have an app that is secured via Auth0.com, on which I've enabled social login via Google and Microsoft. Everything works fine with the former and personal MS accounts work too.

But we’re finding that multiple of our clients who use MS for their organisation email are getting the below error.

I have verified that the Azure app I set up to connect to Auth0 supports all types of MS account, not just personal ones, as the below shows:

I've also set up redirect URLs, permissions etc. As I say, personal MS logins work fine.

Does anyone know what might be wrong?

I read somewhere that you need to connect your app to your Azure directory, or some such. But don't the settings above suggest everything is set up, particularly if some MS accounts can already login successfully?

Many thanks in advance.

Hi @mitya33
Could you please help me with steps you have followed to configure the application, and may I know which authority URL is using in application?

sending the request to https://login.microsoftonline.com/common authority URL all the users from other tenants and personal accounts should be able to access.
Kindly check and confirm the above as per the below document.
