Using MFA and conditional access in the same tenant

Copper Contributor


In our 365 tenant we started with using multifactor authentication per user and we applied Azure AD Multi-Factor Authentication for all users.

Subsequently, we created conditional access to impose the use of multi-factor authentication for all for all users.

To create conditional access, we used an Azure AD Premium license which was assigned to only the administrator account.

All other accounts do not have an Azure AD Premium license, they use office 365 business or standard accounts.

My questions are :

Is it necessary to assign an Azure AD Premium license for each user?

Is it correct to keep Azure MFA and Conditional Access running at the same time?
