Running MS Exchange 2007 Server w/latest updates and sp. I have a few computers that I am unable to create Outlook Mail profiles for (Outlook 2003 & 2007). I enter in the Microsfot Exchange Server, and then the Username. I click the "Check Name" button and then the username/password box comes up. Enter the password in, but it does not recognize it and it is the correct password. I click cancel on the login box and noticed that it does recognize the user name because it underlines it. Doesn't matter who I log in as, and it's only a few workstations. All other network programs work fine. OWA works. I've created test accounts, checked IIS settings, restarted server. Really weird. Any suggestions would be greatly appreciated.
