Signing in error : The user account **** does not exist in the **** directory.

Question

Hi Community,

I'm trying to set up third-party IdP sign-in for Office 365 apps using a federated domain. I've made the necessary changes using Microsoft APIs, and when I try to sign in via portal.office.com or portal.azure.com, I'm correctly redirected to my IdP login page.

My domain ends with @test.com, and I already have a user (******@test.com) created both in Azure AD and in my IdP.

However, after entering the correct credentials on the IdP page, I'm redirected back to Azure and receive the following error:

**The user account ****@test.com does not exist in the <tenantid> directory. To sign into this application, the account must be added to the directory.

I did verify the user exists and UPN name is same too but still it says user doesn't exist in the directory.

I'm not sure what I'm missing. Any ideas on what could be causing this issue?

Thanks in advance!
