Two-factor authentication on a single mailbox

Question

I want to test two-factor authentication on a single mailbox in a hybrid Exchange environment before implementing it company-wide. Is that possible?

Hi @LTSAdmin

Yes you can do this using Conditional Access Policies. You can use the following guide to create a policy for MFA (All Users):

https://learn.microsoft.com/en-us/azure/active-directory/conditional-access/howto-conditional-access-policy-all-users-mfa#create-a-conditional-access-policy

When you are choosing Assignments just assign to to a single user by selecting Select users and groups. (Do not use All users as this will assign the policy to everyone).
