Clearing Old Passwords from Outlook

If you have changed your password, but your old password is stored, or cached, in your computer, you will get error messages as you attempt to log in to Outlook or will continue to be prompted to enter your password. Follow the directions below to clear it. 

Close Outlook.

Click Ctrl-Alt-Del > Task Manager.

Make sure Outlook.exe is really not running in the list. If it is, click it, then click End Task.


To remove the user credentials from Credential Manager:


  1. Click Start > Control Panel > User Accounts > Credential Manager.
    • Note: If 'View by' is set to Category, click User Accounts first, and then click Credential Manager.

    • Note: For Windows 10 users, if you have trouble finding the Credential Manager you can do a quick "Windows Search" or "Cortana" Search from the home screen's taskbar.

4. Repeat step 3 for any additional sets of credentials that have the word Outlook or Microsoft Office in the name.
