I am running Exchange 2013 on Server 2012. Windows 7 clients with Outlook 2010 work fine. Windows XP clients with Outlook 2010 prompt for credentials (user name and password) each time Outlook is started, and checking the "Remember my password" box does not prevent this from happening the next time. The "Always prompt for logon credentials" checkbox on the "Security" tab of the "More Settings" section of the Exchange account is not checked.
Please help me to get this fixed.
