Have a look of the link above. You need to acquire the appropriate licence before the users can use MFA.

Hello, <br />
<br />
I have enabled Multifactor Authentication using phone authentication for a user in the Office 365 portal. &nbsp;<br />
<br />
I am able to use the new app-code to sign to Outlook and OWA. &nbsp;<br />
<br />
My email account in my mobile phone still using the old password I think. &nbsp;How is the new MFA app-code being applied to it?<br />
<br />
Also, how do I enable MFA for group of users? &nbsp;<br />
<br />
Thanks.
