How can I prevent external invited users (Guests) from RBAC assignments?

Fausto Pichardo 0 Reputation points

I have a security need to govern role assignments. In my use case, I need to prevent RBAC assignments to guest/external users in my tenant. My initial thought is to use Azure Policy, but after countless hours of editing custom code and seeking Microsoft assistance, I am no closer to a workable solution. Thanks in advance

    @Fausto Pichardo Thank you for reaching out to us, As I understand you want to prevent guest accounts from showing up or list of guest accounts should not show up while performing RBAC, is my understanding is correct ? Also please me with the case number which you worked with us on this issue to understand what all steps have been taken.
