The client does not exist or is not enabled for consumers.

I am encountering the same error on Drupal 11.1.1 with PHP 8.3.

I am using an organization account. Are you also using an organization account, @zebda?

I'm using a work/school account, is that the same?

I think our problem might be related to this issue: https://www.drupal.org/project/social_auth_microsoft/issues/3159996 💬 Authenticating with an organization email doesn't work Active .

This is likely because we are using "organization accounts," which are not standard email accounts like xxxxx@outlook.com or xxxx@hotmail.com.

I don't think this is related because I'm not even able to enter an e-mailadres. Just going to /user/login/microsoft gives me the error.

I tried again creating the app registration and for some reason it works now...except for the organizational accounts 😔.
