Outlook continues to prompt for credentials after your domain password changes

If you are unable to install the latest update for Outlook 2010 or Outlook 2013, you can work around this issue by removing all previously saved credentials. To remove stored credentials and force Outlook to use your Windows desktop credentials, follow these steps.

1. Click Start, click Control Panel, and then click Credential Manager.
   
   Note If View by is set to Category, click User Accounts first, and then click Credential Manager.
2. Locate the set of credentials that has Outlook in the name.
3. Click the name to expand the set of credentials, and then click Remove from Vault.
4. Repeat step 3 for any additional sets of credentials that have the word Outlook in the name.
