Hi,
We are interested in the features provided by Azure Active Directory like security, multi-factor authentication, scalability, availability, etc.
Our requirement is that we would like the user to use any arbitrary email like user1@outlook.com or user1@gmail.com as the user id. The user may also choose to use user1 as the user id.
We found that we cannot use any string/email as the user id in Azure Active Directory. We found that it only allows user ids of the following format:
1. user1@mydirectory.onmicrosoft.com
2. user1@mycustomdomain.com
What is the recommended way of implementing this in Azure?
Thanks.
