Guest users often come from different environments, which makes it hard to enforce consistent security.

In this quick 20‑minute session, we’ll look at cross‑tenant access settings for B2B guests in Microsoft Entra, showing how it can reduce friction by accepting MFA that’s already been satisfied, while still enforcing device compliance to ensure guests meet standards, though not always the ones you expect.

We’ll use short demos to show how to configure these policies and settings and what guests experience when they sign in.

By the end, you’ll know how to configure guest trust, when it’s the right fit, and when it’s not.

You will learn:

  • How to configure guest trust with cross-tenant access settings in Microsoft Entra
  • About the limitations of device compliance and MFA access tokens through cross-tenant access settings
  • When it's the right fit, and when it's not
