Logging onto SharePoint on a Different Domain causes Outlook 2010 to ask for credentials
I have a user that occasionally logs into a client's SharePoint site via Internet Explorer. When he chooses to save his credentials in IE, a couple of minutes later, his Outlook 2010 is prompting him to re-enter his credentials. Can anyone tell me why this is happening and how I can have him store both without re-prompting for his credentials? Our domain is Windows 2003 R2 based.
