Hi All This problem is driving me and my client crazy, just installed SBS2008 server all seemed to go well. Then when trying to setup users email accounts I had problems finding the server to authenticate the mail in Outlook Profile setup. It pops up with box asking me to connect to Sites and then asking for username/password - no matter what combination i use it wont go away. After retring it does eventually tick the box. But when opening Outlook 2007 it again prompts for the username/password and the user does not get there mail. I did find a way to stop this in IIS 7 Application Pools stop the AutoDiscoverRecovery and it works only problem in doing that Offline address book does not work neither does Out of Office Assitant. Please help Thanks Jason
