Using classic Outlook for Windows in educational settings
Hi @Sasja Elliott,
Thank you for posting your question in the Microsoft Q&A forum, and I’m sorry to hear you're having trouble accessing your college account due to Microsoft Authenticator app.
The lockout occurred because Microsoft’s Multi-Factor Authentication (MFA) relies on the Authenticator app as the primary verification method. When the app is signed out or removed, it can no longer generate valid codes, and password resets still require MFA for security. Without a backup method (like SMS or alternate email), the system defaults to the app, creating a loop. This design prevents bypassing MFA to protect accounts.
Since you are using a work or school email address, the MFA settings are managed by your college's IT department. For assistance with resetting or updating your MFA, you will need to contact them directly to resolve this.
Please contact your college's IT Help Desk or support team and explain the situation. You can say: "I am stuck in a login loop between Microsoft Outlook and the Microsoft Authenticator app. I cannot get the code to sign in."
Specifically ask them to “Reset my password and MFA settings or allow me to re-register for MFA". This is a standard request, and your college's IT team should be able to assist you with it.
You can also share the steps in this Microsoft article for them so they can help reset your MFA settings for you Manage user authentication methods for Microsoft Entra multifactor authentication.
Once your school's IT admin has reset your MFA, the next time you log in to your account, you will be guided through the process of setting up the Microsoft Authenticator app again from the beginning by scanning a QR code. This will break the loop and allow you to access your account normally.

While we do not have access to internal systems or administrative tools required to resolve account-specific or backend-related issues but we’ll continue doing our best to support you within the scope of our responsibilities.
I hope this helps you regain access to your account quickly. I'm glad to assist and truly hope the information provided has been useful. Please feel free to reach out anytime if you need further assistance.
