How to Stop Microsoft 365 from Opening a Former Employer's Sign-In Page

Product: Microsoft 365
Device & OS: Windows
Scenario: Attempting to sign in to a personal or new work Microsoft 365 account on a Windows computer previously used for a former job.
Observed behavior: The Microsoft 365 login screen persistently redirects to a former employer's sign-in page, preventing access to the current account.

Before you start

Save any open work and ensure you have local administrator privileges on your Windows computer, as you will need to modify system account settings and restart the device.

Solution 1Recommended

Disconnect the Former Employer's Account in Windows Settings

Use this solution to remove the organizational link that forces your computer to route Microsoft 365 traffic through your previous employer's tenant.

Open Windows Settings

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

Navigate to Account Settings

Click on 'Accounts' from the main settings menu, then select 'Access work or school' from the left-hand sidebar.

Disconnect the Account

Locate your former employer's account in the list, click on it, and select the 'Disconnect' button. Follow any on-screen prompts to confirm the removal.

Restart Your Computer

Once the account is disconnected, restart your computer to ensure the changes take effect and the system clears the organizational policies.

Device Management: If the 'Disconnect' button is missing or grayed out, your computer may be fully managed by your previous employer's IT department. You will need to contact them to unenroll the device.

Solution 2

Remove Saved Credentials from Windows Credential Manager

Clear cached login details that might be automatically feeding your old work credentials into Microsoft 365.

Solution 3

Clear Browser Cache and Check Startup Pages

If you are using the web version of Microsoft 365, your browser may be caching the old employer's login URL.

Frequently Asked Questions

Why does Microsoft 365 keep redirecting to my previous employer's login?

This happens because Windows caches your organizational account connection under the 'Access work or school' settings, or your browser and Windows Credential Manager have retained the login tokens from your previous job.

Will disconnecting my old work account delete my personal files?

No. Disconnecting a work or school account only removes the organizational link, corporate policies, and employer-managed applications. Your personal files and data stored locally on the computer will remain intact.

What should I do if the 'Disconnect' button is missing?

If you cannot disconnect the account, your device is likely still enrolled in your former employer's Mobile Device Management (MDM) system. You will need to contact their IT department to remotely unenroll or wipe the organizational management from your computer.
