After the password for your domain user account is changed, Microsoft Outlook 2010 and Microsoft Outlook 2013 may prompt you for your password. After you enter the new password and then click to enable the Remember my credentials option, you are not prompted again during the current Windows session. However, if you log off Windows, log back in, and start Outlook, you are again prompted for your credentials.
Before your password changed, you saved your credentials. The stored credentials are not overwritten when Outlook triggers the authentication prompt even if you enable the Remember my credentials option.
To resolve this problem, install the latest update for Outlook 2010 or Outlook 2013. For more information about the latest updates for Microsoft Outlook, click the following article number to view the article in the Microsoft Knowledge Base:
