Answer 2

Hello Afahtullah Akmal Mohamad,

Good day to you and thanks you for your post in Microsoft Community.

Regarding your query, for one of the affected user check with delete sign-in method first from his/her account and then contact your Microsoft365 Admin and ask admin to reenable MFA for that user account from Microsoft365 Admin center. At the time of reenable MFA settings, select “Require selected users to provide contact method again” (as per below screenshot) option and then check. After reenable MFA, asked the affected user to login his account with clear browser’s cache or use InPrivate browser mode and check.

We look forward to your response.

Thank you so much for your precious time and kind cooperation.

Hello Afahtullah Akmal Mohamad,

Good day to you. For this, you can remain few verification methods as it is.

For re-enable MFA, we suggest you to try with Microsoft365 admin center via go to Active users > select one of the affected user > go to Manage Multifactor authentication and then disable it and after few times enable it again. And select “Require selected users to provide contact method again” and check.

Thank you so much for your precious time.
