i have a user who recently migrated from and NT domain to Server 2003 as a test subject. When he did that, he was set up with Office 2007. Now when he goes to open the public folders tab to access a public folder, he gets a login prompt. onve he enters his info he is then able to access the public folders. This is in a Child domain of our network. We are in a mixed exchange environment of 2003 and 2007.
