My consultant Stuart Malone <xxxxxxxxx> has not been able to log in to my Azure Portal since upgrading his iPhone. He has a guest account under the address xxxxxxxxx.onmicrosoft.com.

We performed a 2FA reset and his new iPhone now lists his guest account in Microsoft Authenticator. However, every time he logs in to the portal, even from a private browser window and using the full #EXT# email address, he is redirected to his work account under xxxxxxxxxx instead of the guest account in my Azure Portal.

How can he regain access to his guest account.

You can contact him directly at XXXXXXXX.com or YYYYYYY.
