Accessing Outlook on the web for business using organizational credentials.
If you are not receiving the verification code needed to sign in, and restarting your phone or requesting a new code has not resolved the issue, please contact your school's IT Support team or Help Desk as soon as possible. They can verify your identity and reset or update your Multi-Factor Authentication (MFA) settings. In many cases, a missing verification code is caused by an issue with the registered phone number, authentication method, or MFA configuration on your account, which only your school's IT administrators can modify.
Please contact your school's IT administrator or support team and ask them to complete the following steps:
- Sign in to the entra.microsoft.com as at least Authentication Administrator.
- Select User -> All user. Select the user (your account) to act on and select Authentication methods. then select Require re-register of multi-factor authentication.
- Require re-register MFA: This disables all previous authentication methods. You'll then be prompted to configure a new MFA authentication method the next time you try to sign in, so you can set up from the start and add a new authenticator app.
For more details, please refer to: Manage user authentication methods for Microsoft Entra multifactor authentication.
Find Your Microsoft 365 Admin: If you're unsure who manages Microsoft 365 accounts for your school, please contact your school's IT Help Desk, Technology Support team, or Student Services office, you can find guidance on locating them here: How do I find my Microsoft 365 admin?
Note: Once re-registration is triggered, all your existing MFA methods such as phone numbers, Authenticator app, or other verification options will be removed. You will need to set up new MFA methods during your next login. Please ensure you have access to a valid phone number or the Microsoft Authenticator app before attempting to sign in again.
