Hi Baijin Numveragi,
Thank you for reaching out to us. I'm glad to help you!
Based on my understanding, you're currently experiencing a problem with your Microsoft Authenticator app when trying to scan a QR code, which is preventing you from adding your Microsoft 365 Business email to the Outlook app. It also seems like there might be some confusion between your business account and an academic account during this process.
To help me assist you best, could you please provide a bit more information:
- What's the exact error message that appears when you try to scan the QR code? If possible, could you take a screenshot of the error and send it to me?
- Are you currently able to sign in to your Microsoft 365 Business account on a computer? (by using your regular password, or getting a code via SMS without needing the Authenticator app?)
- Are you an end-user of this Microsoft 365 Business account, or are you an admin?
While I await your reply, please help me try this one if you are an end-user/admin - still have access to your work account on your computer and you have permission to set "Authenticator app" as your new sign-in method in the "Security info" section of your Microsoft 365 account:
Please uninstall the Microsoft Authenticator app completely from your phone. Restart your phone. Then, download and reinstall the Microsoft Authenticator app from your phone's app store.
On your computer, please try signing out of all Microsoft accounts (including any academic accounts) in your web browser. Open your browser in an incognito/private window. Sign in to your Microsoft 365 Business account portal (usually via myaccount.microsoft.com or your admin portal if you're an admin). Look for the "Security info" > Delete and add a new sign-in method and select "Authenticator app." Follow the prompts to display a new QR code, and then try scanning this new code with the Authenticator app you just reinstalled on your phone.
If you are unable to change (remove or add) the Authenticator (MFA) settings yourself in the "Security info" section, it means that your company may have set up its own security policy. In that case, please help me answer the questions above, and I will guide you through the next steps.
Once I receive more information, I can provide the steps to help you. Please understand that our initial response may not always resolve the issue right away. But with your help and a bit more detail, I'll try my best to help you.
Looking forward to your reply!
Sincerely,
