SC-300 Certification Practice Question #51

Question

You have an Azure AD tenant that contains the external user shown in the following exhibit.

You update the email address of the user.

You need to ensure that the user can authenticate by using the updated email address.

What should you do for the user?

Accepted Answer

The user is an external/Guest B2B account (UPN contains `#EXT#`, User type = Guest, B2B invitation state Accepted, as shown in the exhibit). After changing a redeemed guest's email, MS Learn states you must reset the redemption status so the user can re-redeem and sign in with the new email while preserving their object ID, group memberships, and app assignments — precisely this scenario. None of the alternatives change the identity/email a guest authenticates with. Suggested Answer, the dominant community vote (15), a 14-👍 cited comment, and MS Learn all converge, so confidence is high at 95%.
