Logging onto SharePoint on a Different Domain causes Outlook 2010 to ask for credentials

Hello Experts,

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.

Thanks!

I have also come accross this issue, when the user name is identical on both domains. I never did get a resolution other than changing user name.

Thank for the links, but it still doesn't resolve my user wanting to save the sharepoint credentials on the Internet on a different domain while keeping his Windows logon credentials for our domain.

Is there a way to store both SharePoint (client's domain) and Exchange (our domain)?

I believe that the problem is caused by Basic Authentication being disabled by default with Office 2010.

Here's the Microsoft KB article for the changes needed to enable Basic Authentication:

Hope this helps.
