How to Fix Outlook Repeatedly Requesting a Security Code

Product: Microsoft Outlook
Device & OS: Windows
Scenario: Adding a personal Outlook.com account to Microsoft 365 Apps for enterprise on a personal computer.
Observed behavior: Outlook repeatedly prompts for phone verification and loops continuously without progressing to the Windows Hello PIN setup.

Before you start

Ensure you have your correct personal Microsoft account credentials ready and verify that you have administrator access to your Windows computer to modify account settings.

Solution 1Recommended

Remove Outdated Work or School Accounts from Windows

Clear old organizational credentials from your Windows settings, which are often the root cause of the verification loop.

When older work or school account profiles remain active on your personal computer, they can interfere with Microsoft 365 Apps authentication. Removing these outdated connections forces the system to rely only on your active personal credentials.

Open Windows Settings

Click the Start button and select the gear icon to open Windows Settings. Alternatively, press Windows Key + I on your keyboard.

Navigate to Accounts

Click on 'Accounts' and select 'Access work or school' from the left-hand menu pane.

Disconnect the Outdated Account

Locate any old or unused work or school accounts in the list. Click on the account and select 'Disconnect', then confirm the removal.

Restart Your Computer

Restart your PC to ensure the credential cache is fully cleared from the system memory.

Add Your Account in Outlook

Open Outlook and attempt to add your personal Outlook.com account again. Complete the required multifactor authentication steps normally.

Remove Outdated Work or School Accounts from Windows

Authentication Resolved: Once the conflicting accounts are removed, Outlook should bypass the loop and correctly initiate the Windows Hello PIN setup if required.

Solution 2

Clear Saved Credentials in Windows Credential Manager

Use the built-in Windows Credential Manager to manually delete stubborn Microsoft Office login states.

Frequently Asked Questions

Why does Outlook keep asking for my security code in a loop?

This usually happens when Outlook detects conflicting cached credentials from old work or school accounts. Windows prioritizes these enterprise credentials, causing an authentication loop when adding a personal account.

Can I bypass the multifactor authentication (MFA) in Outlook?

It is not recommended and often impossible to bypass MFA if your account requires it. Instead of trying to bypass it, ensure you clear old credentials from Windows settings and complete the MFA prompt using the Microsoft Authenticator app or an SMS code.

What should I do if the Windows Hello PIN setup never appears?

If the Windows Hello PIN setup is skipped or blocked, go to Windows Account Settings > Sign-in options, and ensure Windows Hello is configured correctly. Disconnecting outdated enterprise accounts in the 'Access work or school' menu usually resolves the blockage.

Will removing a work account delete my personal files?

No, disconnecting a work or school account from Windows Settings only removes the organization's access policies and credential tokens from your device. Your personal files and local data remain untouched.
