n11my (n11my) asked a question.
We have deployed MFA (not adaptive) and are struggling with getting the remainder of users enrolled/registered as we are not aware of a solid solution to force a user to register and enroll a device. it's been a slow roll, we have already sent out a second email to all users who have not registered. Is their a technical solution within Okta or anything that has worked for you?
Background: Only enforcing it on O365 resources while user is off the network

Hi Obai,
In order to force users to enroll you must set at least one factor as required and in the rule you must select when the user first sign in. This will force users to enroll to designated factor on the next login.
Also there is an option in MFA enrollment policy to choose a specific application when MFA should be enforced. This is an EA feature which you will have to request to Okta Support by submitting a support case. You can set the IP zone too in a policy, More details available here under section "Multifactor Policies" https://help.okta.com/en/prod/Content/Topics/Security/MFA.htm .
