Weird issue with MFA for Guest Users
Hey, we have implemented MFA for external Guest Users in Entra ID. It is working fine for every external user so far. However, there are two users from the same external company who cannot get in...
Hello ehalmiTke,
thank you for your response.
As mentioned, those are external guest users which were invited into our environment. They are just trying to access Teams and/or SharePoint.
We are not their identity provider nor do we have SSO implemented for them.
They are not receiving a MFA prompt when trying to enter our environment, they just get greeted with the SAML error.
I am a bit confused, since I can't see the connection between the error and the missing MFA prompt for an external user.

You can use fiddler to investigate what is happening. My suggestion is provided as the error indicate SAML, hence SSO is happening on the backend.
