![]() ![]() In the left navigation, click Voice > Phone numbers. This is usually the account you used to sign up for Microsoft 365. Open the Microsoft Teams admin center and log in with a user that is a Global admin. To assign a number by using the Teams admin center: When assigning a phone number to a user, make sure the phone number and the usage location of the user are of the same country. If you want to assign a Calling Plan or Operator Connect phone number to a user or resource account, you must ensure that any phone number stored in the msRTCSIP-Line attribute on the user or resource account object in the on-premises Active Directory has been removed, and the change has been synchronized to Microsoft 365. ![]() This ultimately allows for a semi-suitable workaround because it allows an administrator to clear the old phone number so the user is re-prompted, but it is definitely a bug and prevents the administrator from viewing the existing phone number for verification purposes, which results in reduced security.This note applies to customers who have a hybrid deployment with an on-premises Active Directory. However, the bug appears when you go to administer the MFA phone number using the Graph API methods under /authentication/phoneMethods/3179e48a-750b-4051-897c-87b9720928f7 B2C accepts this value and subsequent MFA requests work just fine. When this value is written back to B2C under Users->Authentication Methods->Phone, it does so in the format +12223334444 with no space in between the country code and the area code. The B2C technical profile name is AAD-UserWritePhoneNumberUsingObjectId. We are using B2C custom policies with a step to write back the user's MFA profile to the B2C profile. How do I programmatically clear or update a phone number for Azure AD B2C MFA? This was suggested by Hari Krishna on another thread to open a new SO thread for this discussion. ![]()
