How to Remove a Saved Office 365 Account from the Login Page

Product: Office 365
Device & OS: Windows
Scenario: Cleaning up shared computer login credentials or removing an old work or school account from the login portal.
Observed behavior: An Office 365 account username continues to appear on the sign-in page even after selecting the 'Forget' option, often restored by browser autofill or Windows Credential Manager.

Before you start

Before modifying your system credentials, completely close all active Microsoft Office applications and browser windows to ensure cached data is fully released.

Solution 1Recommended

Clear the Account from Sign-in Page and Credential Manager

The most effective way to remove lingering Office 365 accounts is to forget the account on the initial screen and delete the saved Windows credentials.

Windows often stores Microsoft account tokens securely in the background. Removing it from the browser alone may not be enough if Windows Credential Manager automatically supplies the saved login.

Forget account on the sign-in page

On the Microsoft 'Pick an account' sign-in page, click the three-dot menu next to the account you want to remove and select 'Forget'.

Open Windows Credential Manager

Open the Windows Control Panel, navigate to 'User Accounts', and then click on 'Credential Manager'.

Locate Microsoft credentials

Select the 'Windows Credentials' tab and scroll down to the 'Generic Credentials' section to locate any entries related to Microsoft Office, OneDrive, or Office 365.

Remove the saved credentials

Click the down arrow next to the corresponding Microsoft credential and select 'Remove' to delete it from your system.

Clear the Account from Sign-in Page and Credential Manager

Prevent Future Device Administration: When signing in again in the future, uncheck the 'Allow my organization to administer this device' option and click 'No, sign in to this app only' to prevent Windows from saving the account globally.

Solution 2

Clear Browser Autofill and History Data

If you primarily use Outlook on the web or Office 365 online, your web browser's autofill settings might be automatically restoring the old account information.

Frequently Asked Questions

Why does my Office 365 account keep reappearing after I click 'Forget'?

This typically occurs because the account credentials are saved securely in the Windows Credential Manager or your web browser's autofill settings. The 'Forget' button only clears the local page cache, so you must clear the data from your system settings to permanently stop the prompt.

Will removing the Office 365 account from the login page delete my files?

No. Removing an account from the sign-in page or the Windows Credential Manager only deletes the saved login username and password on that specific device. Your cloud files, documents, and emails remain safely stored on Microsoft's servers.

How do I stop Windows from automatically saving my work account?

When you sign in to a Microsoft application for the first time, a prompt asks if you want to 'Allow my organization to administer this device'. If you uncheck this box and instead click 'No, sign in to this app only', Windows will only authorize that single app and will not save the account to your system globally.
