How to Remove Old Work or School Accounts from Windows and Office

Product: Windows and Microsoft Office
Device & OS: Windows
Scenario: Cleaning up outdated work or school credentials from a personal computer and phone to prevent sign-in conflicts and unwanted login prompts.
Observed behavior: Old organization accounts remain cached in Windows, Office applications, and the Authenticator app, causing the system to continuously attempt logging into the former profiles.

Before you start

Ensure you have your personal Microsoft 365 account credentials ready, as clearing cached data may require you to sign back into your Office applications.

Solution 1Recommended

Clear Cached Accounts in Windows Credential Manager

Remove lingering account details directly from the Windows system level to stop Office from automatically attempting to use old credentials.

Windows stores login information for applications and websites in the Credential Manager. Clearing these cached files is the most effective way to resolve persistent sign-in prompts from former work or school accounts.

Open Credential Manager

Click the Windows Start menu, type 'Control Panel' and press Enter. Navigate to User Accounts, then click on Credential Manager.

Locate Old Credentials

You will see two tabs: 'Web Credentials' and 'Windows Credentials'. Review the lists under both tabs for any entries mentioning MicrosoftOffice, your old organization email, or former school accounts.

Remove the Entries

Click the downward arrow next to the unwanted credential to expand it, and select 'Remove'. Confirm the deletion and repeat this process for all old account entries.

Clear Cached Accounts in Windows Credential Manager

System Restart Recommended: After clearing your credentials, restart your computer and open an Office application to sign in fresh with your personal account.

Solution 2

Disconnect Accounts from Windows Settings and Office

Unlink the organization profile from your overall Windows 10/11 environment and manually sign out from Office apps.

Frequently Asked Questions

Why does my old work account keep appearing in Microsoft Word?

Microsoft Office applications cache your login credentials to make signing in faster. If you haven't removed these details from the Windows Credential Manager, Office will continue to detect and suggest the old work account.

How do I remove a school account from the Microsoft Authenticator app on my phone?

Open the Microsoft Authenticator app on your mobile device. Tap on the specific school account you wish to remove, tap the settings gear icon (or the three-dot menu in the top right), and select 'Remove account'.

Will disconnecting my work account delete my personal files?

No, disconnecting a work or school account from Windows or Office only removes the login credentials and restricts access to organization-specific cloud files on OneDrive or SharePoint. Your locally saved personal files will remain completely untouched.
